2Standard DP motors
2.1General
Standard DP motors are produced conform the latest technical design, and comply with the international standards and EU directives regarding safety measures. For motor specifications, please consult your supplier.
General motor specifications
• AC squirrel cage induction motor.
• T.E.F.C. Totally enclosed fan cooled.
• Protection IP55 (single phase IP54).
• Insulation class F.
• Temperature rise class B.
• Noise levels conform IEC 60034-9.

• All ball-bearings from frame 71 and 80 with grease -30 °C + 130 °C
• All ball-bearings from frame 90 and up with grease -30 °C + 160 °C
Using a motor with a different bearing on the driven end, consequently leads to a different expected lifetime of the motor.
When the motor bearing is damaged the axial position of the pump shaft is incorrect which could lead to extreme damages of the hydraulic assembly of the pump.
2.4Fixed axial play
Regarding the above mentioned, it is also important to avoid axial movement of the motor shaft, which directly influences the axial position of the pump shaft and impeller in relation to the diffuser. An incorrect position of the hydraulic assembly could influence the hydraulic performance of the pump (Internal leakage or flow disturbance per stage).
2.5High temperature grease
ATTENTION
Only applicable for motors of 1.5 kW and up!
When the motor is subjected to the maximum load and the ambient temperature is high (up to maximum 40 °C), the winding can reach its maximum allowable temperature difference of Δt=80 °C (insulation class F/ temperature rise class B). In these situations it is
important that the bearing grease does not lose its ability to function and shorten the lifespan, caused by losing its lubricating properties or because it becomes too fluid which can cause the bearing to lose the grease.
At long term running, the bearings could lose their grease and shorten the lifetime of the motor bearing.
2.6Smooth shaft without keyway
The pump shaft (210) is coupled to the motor shaft with a clamp coupling (862). To avoid imbalance and to insure maximum grip between the shafts and the coupling, the motor shaft is not provided with a keyway.
In case of a special / other brand motor which is provided with a keyway, it is recommended to assemble a half key in the keyway prior to clamping the coupling on the shaft.
2.7Voltage range
To make standard DP motors applicable for most countries and power supply ranges, they have an extended voltage supply range and can be used at 50 Hz and 60 Hz.
WARNING
The motor/pump combination must be selected for 50 Hz or 60 Hz operation.

2.8Nominal current
The current of the motor depends on the load, used voltage and frequency. On pumps of design version B, motors ≥ 0.75 kW are not subjected to a load higher then the nominal power output. Therefore the current as mentioned on the nameplate of the motor is the value which is to be used to protect the motor/ pump combination. No current will be mentioned on the nameplate of the pump.
2.9Motor temperature ratings
The electric motor's insulation system separates electrical components from each other, preventing short circuits, winding burnout and failure. To prevent failure of the insulation it is important that it is not subjected to temperatures to which it is not resistant.
A thermal class (insulation class) is used to indicate the maximum temperature at which the insulation is designed to be able to operate for a long and predictable running life of 20,000 hours or more. The table below provides a summary.
Insulation system class (NEMA) B F
Temperature Rating (Maximum Winding Temperature) 130 °C155 °C
Temperature Rise Allowance by Resistance (Based on 40° C Ambient Temperature)
1.When operating at service factor loading, the hot spot temperatures can exceed the insulation rating, resulting in shortened motor life. 115 °C1
The table shows the temperature ratings, temperature rise allowances and hot spot allowances for various enclosures and service factors of standard motors. The table also shows the highest allowable stator winding temperatures for long insulation life.
The standard motors for the V(S) are designed to operate cooler than their thermal class allows. The standard motors have Class F insulation with a Class B temperature rise. This gives an extra thermal margin.
2.9.1Ambient temperature
Ambient temperature is the temperature of the air surrounding the motor or the room temperature in the vicinity of the motor. This is the temperature that the entire motor would assume when it is shut off and completely cool. The basic ambient temperature rating point of all standard motors is 40 °C.
2.9.2Temperature rise
Temperature rise is the change in temperature of the critical electrical parts of the motor when it is being operated at full load. If the motor is located in a room with a temperature of 20 °C, and operates continuously at full load, the winding temperature rises from 20 °C to a higher temperature. The difference between starting temperature and final elevated temperature, is the motor’s temperature rise. The amount of temperature rise is always additive to the ambient temperature.
2.9.3Hot spot allowance
The average temperature rise of a motor can be determined by measuring the difference between the cold and hot ohmic resistance of the winding. As
Figure 3: Insulation classes
Table 8: Insulation system class
there will always be regions inside a motor that are hotter then others, an allowance is added to the average temperature to indicate what the maximum temperature is. This is called the 'Hot spot allowance'.
2.9.4Insulation class
Standard DP motors are designed with insulation class F - B-rise. This means that the motor is capable to withstand temperatures according to class F but at nominal power will only have an increase in temperature according to class B.
This difference in thermal capability be used to allow for:
• Higher ambient temperatures
• (Limited) overload
• High or low voltages, voltage imbalance, blocked ventilation, high inertia loads, high frequent starts
• Operation in environments with lower ambient pressure
• Any other factors that can produce above normal operating temperatures
• Applying a motor at lower powers extends the motor life expectancy
2.9.5Insulation life
Insulation life is affected by many factors aside from temperature. Moisture, chemicals, oil, vibration, fungus growth, abrasive particles, and mechanical abrasion created by frequent starts, all work to shorten insulation life. On some applications if the operating environment and motor load conditions can be properly defined, suitable means of winding protection can be provided to obtain reasonable motor life in spite of external disturbing factors.
2.10Rotational speed
The rotational speed depends on the supply frequency, the characteristics of the motor and on the torque/speed curve of the pump. Hydraulic and power curves are plotted at fixed speed. This speed will approximately be the same as the speed at optimum pump efficiency.
As the load increases with the frequency it is important that the combination of motor, pump and frequency is chosen correctly to prevent overload of the motor.
Keep in mind the rotational speed is:
linear to capacity(n2/n1)1 =(Q2/Q1)
squared to pressure(n2/n1)2 =(p2/p1)
cubic to power(n2/n1)3 =(p2/p1)
e.g. A motor with a nominal speed higher then listed in Table 9 Values for the rated P/frame size and max speed might not have sufficient power.
Table 9: Values for the rated P/frame size and max speed
All standard DP motors meet the last version of the EuP Directive 2009/125/EC (ecodesign requirements) and of the Commission regulation implementing 2009/125/EC.
The requirements are:
• from 16 June 2011, motors shall not be less efficient than the IE2 efficiency level
• from 1 January 2014, motors with a rated output of 7.5 - 375 kW shall not be less efficient than the IE3 efficiency level or the IE2 efficiency level and be equipped with a variable speed drive.
• from 1 January 2017, motors with a rated output of 0.75 - 375 kW shall not be less efficient than the IE3 efficiency level or the IE2 efficiency level and be equipped with a variable speed drive.

2.12Efficiency and power factor
The total power required by an inductive device as a motor or similar consists of:
• Active (true or real) power (measured in kW)
• Reactive power - the non working power caused by the magnetizing current, required to operate the device (measured in kilovar, kvar)
The power factor defined by IEEE and IEC is the ratio between the applied active (true) power - and the reactive power, and can in general be expressed as:
PF = P / S
where
PF = power factor (or cos φ)
P = active (true or real) power (W)
Q = reactive power (var)
S = complex power (VA)
The power factor for a three-phase electric motor can also be expressed as:
PF = P / [(3)^1/2*U*I*η]
where
PF = power factor
P = shaft power (W)
U = voltage (V)
I = current (A)
η = motor efficiency
This means that when the power factor is low, the reactive power is high. Because the reactive power is not measured but still has to be supplied by the energy company, motor manufacturers make an effort to make the power factor as high as possible within the possibilities of the construction.
The efficiency of a motor is defined as:
η = P shaft / P active . 100 %
where
η (eta) = efficiency
P shaft = power which flows through the shaft (W)
P active = electric power through the mains (W)

Pmotor = Pshaft / η 1000 W power supply400 V

2.13Terminal box position
The position of the motor terminal box can easily be changed by rotating the motor on its motor stool (341)
This can be done by loosening the motor bolts while keeping the coupling (862) adjustments unchanged. When ordering the pump with an optional position of the terminal box following indications are used.
