ZSN4 Cement Turning Round DC motor
General Descriptions:
|
| |
|
The ZSN4 series DC Motors are dominant products of our factory. The products are found wide use for cement machinery, ZSN4 series DC Motor design upon our Z4 series DC motor to manufacture. According Cement Turning Round making specialty to exploitation, |
| |
1, Alititude above sea level maximal 1000m
|
| |
2, Cooling air temperature maximal 40'C |
| |
3, Ambient conditions for motors should be free from acidic, Alkali fumes or other aggressive gases which corrode insulation |
| |
4, Armature and field circuit for motors may be either operated on static thyristor controlled supplies. Or from DC generator |
| |
5, Performances of motors all comply with state standard GB755 《fUNDAMENTAL TECHNICAL RULES FOR ELECTRSCAL MACHINES》 |
| |
Products performance: |
| |
Motor Frame: IEC ZSN4-225~ZSN4-355 |
| |
Output(KW): 40kW~355kW |
| |
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. |
| |
Raged Speed(rpm): 1500r/min, 1000r/min, 750r/min |
| |
Insulation Class: CLASS F |
| |
Protection Class: IP21S and IP44 is adopted for the motors protections of this series |
| |
Mounting Type: IMB3, IM35 |
| |
