DC Motor 132 kw Type Z4-250-31-TH 440V/180V 332A/12,4A 1000/2000rpm

Widely applied in the industry of metallurgy, papermaking, printing, textile, printing and dyeing, cement and machine tools.

General Description

  • Frame sizes: 100-450           
  • Rated output: 1.5-600kW
  • Insulation class: F               
  • Voltage:160V / 440V
  • Duty cycle: S1                  
  • Excitation mode: Separate excitation
  • Rotation speed: 3000,1500,1000,750,600,500,400,300,200r/min

Great speed control system by which speed can be reduced by lowering voltage with constant torque or raised by lowering exciting current with constant output; wide range of speed regulation; small size, lightweight; high output power, EPT overload capacity.

Altitude not exceeds 1000m, highest ambient temperature shall be no higher than +40ºC;can’t work in the circumstance where acidic/alkaline gas, or some other gas that may damage the insulation exist; the motor powered by rectifier supply; standard exciting voltage is 180V,reinforced excitation is allowed but its voltage can bot be higher than 500V.

2. Cooling method
This series motors are cooled by forced air with separated built-on blower which is connected to independent power supply, and also fitted with air filter. The cooling method of the motor is IC06, motor of IC17, IC37 can also be customized.
 a. Z4-100~Z4-160, blower locates at NDE
 b. Z4-180~Z4-450, blower locates at DE
c. Parameter of the cooling air and blower motor power see table (three phase, 2 poles, 380V).
    Noted: Consult the producer when clients are interested in the following type motor:
a. Frame size Z4-100~Z4-225 totally enclosed self-cooled motor (IC410).
b. Frame size Z4-180~Z4-450 separately-cooled motor, blower at NDE (IC06).
c. Frame size Z4-100~Z4-200 self-cooled motor, fan on the shaft (IC01).
d. Frame size Z4-160~Z4-355 totally enclosed motor with air-air cooler (IC666).
e. Frame size Z4-160~Z4-450 totally enclosed motor with air-water cooler (IC86W).

3. Terminal box is at the right side of the frame from the view of DE (The motor whose terminal box is at the left side or on the top can be also customized).
4. Motor whose speed generator or rotary encoder is at NDE can also be customized.
5.  Motor is connected to flexible coupling.
