Brief Introduction

 

The rated output power of the DC motor is slightly lower than that of class A motors with the same center and the same axial length of the foot, and the other data are basically the same. If the class B motor specifications are known, you can also use the Class A specification table to initially select the class B motor, the rated power of the class B motor should be amplified by about 25% during the primary election, and then select the relevant model specifications in the Class A specification table according to the amplified power, but the corresponding model A needs to be changed to B, and the corresponding power is still the unamplified power (that is, the original power of the class B motor). The final model specifications can be agreed between the user and the manufacturer.

 

For example, the use of 96kW 220V 185r/min Class B motor with an amplified power of 25%, corresponding to 120kW 220V 185r/min class A motor with A similar model in the class A specification table:

 

Z450-2A 118kW 220V 178r/min- Change the model to :Z450-2B, this model approximately represents 96kW 220V 185r/min Class B motor can initially meet the requirements of the use of occasions.

 

In addition to the five voltages and the corresponding power speed listed in the technical data table of this series of motors, any specification of the motor can be derived into other grades of voltage (but not exceed the maximum voltage allowed by the specification) and the corresponding power and speed.

 

The conversion relationship is as follows:

 

First of all, in the same type of technical data table to find the UN, nN, PN and the newly derived technical data is closest to the rated voltage, and lower than the newly derived supply voltage, and the corresponding rated base speed and rated power. In general, the higher the voltage and the higher the speed, the greater the output power, and the smaller the vice versa.
