 Model Number |
JU002 |
|
Motor Frame: IEC Z4-100~Z4-450
|
| |
Output(KW): 2.2kW~1400kW
|
| |
Rated Voltage(V): The sandard rated voltage of this series motors are 160V or 440V, Values for 220V or 400V or other voltage may be derived on request
|
| |
Excitation Type: Separate excitation is the basic excitation type of this series motors, Nominal field voltage:180V, Other excitation voltage are also acceptable on request. To assure the reliablity of insulation of excitation system, The motor must be protected againse self-indued voltages by a release resistor connected in parallel with the field winding when the excitation circuit of the motor is interrupted, At rated field winding resistance(cold). While the field voltage is higher than nominal voltage, The value of shunt resistance may be lower than seven-times fields resistance. Otherwise higher than seven-times.
