Setting Up Analysis Parameters for a PMDC Motor
To define the solution data:
- To open the Solution Setup window, right-click Analysis in the Project Manager tree, and click Add Solution Setup.
- Click the General tab. The Operation Type is automatically set to Motor for this machine type.
- Select the Load Type
used in the motor from the following options:
Const Speed
The speed remains constant in the motor.
Const Power
Const Torque
The torque remains constant regardless of the speed. In this case, Tload = Trated, given by the output power divided by the given rated speed.
Linear Torque
The torque increases linearly with speed. In this case, Tload = Trated * (n/nrated) where Trated is given by the output power divided by the given rated speed.
Fan Load
The load varies nonlinearly with speed. In this case, Tload = Trated * (n/nrated)2 where Trated is given by the output power divided by the given rated speed.
- Enter the output power developed at the shaft of the motor in the Rated Output Power field.
- Enter the RMS line-to-line voltage in the Rated Voltage field.
- Enter the desired output speed of the motor at the load point in the Rated Speed field.
- Enter the temperature at which the system functions in the Operating Temperature field.
- Click OK to close the Solution Setup window.
