General Descriptions:
ZYZJ Series Sugarcane Mill Rolling DC Motor, developed on the basis of Series Z4 DC motors, are a kind of serial products for special purpose, which have been made corresponding improvements in designing and manufacturing technologies in accordance with characteristics of the roll drives of sugarcane mills.
1. Data listed in the Technical Data Table should be employed under the following conditions: a. Temperature of primary cooling medium entering motor should not be higher than 40C; b. Environment for operation should be free from acidic or alkali fume or any other aggressive gas which will corrode insulation; c. Motor is of continuous duty(S1); d. Armature and field circuits of motor may be powered either on static thyristor controlled supplies or from DC generator.2. The motors are class F insulated.3. Standard rated voltage of the motor is 440V, 520V, 550V and 660V. Other voltage may be derived on request, but it should be determined through consultation.4. Standard rated speed is 1000, 750, 600, 500 or 400r/min. Decreasing armature voltage to make speed regulating under constant torque, and lowering down field voltage to make speed regulating at constant output. For speed regulating range see the Technical Data Table. At speed regulating of constant torque below rated voltage, the minimum speed can reach 20 r/min with smoothing operation of motor.5. The motors can sustain a current gradient of di/dt= (200 - 250) In/s at speed and load.6. Standard rated field voltage is 220V.Other excitation voltages are also acceptable on request. To ensure the reliability of a release resistor connected in parallel with the field winding when the excitation circuit of the motor is interrupted. At rated field voltage the value of shunt resistance is about six times of field winding resistance (cold state). While the field voltage is higher than rated voltage, the value of shunt resistance may be lower than six times, otherwise higher than six times.7. Performances and technical requirements of the motors all conform to the national standard GB755General requirements for rotating electrical machines, and can also be checked in accordance with IEC 34-1 standard of the International Electrotechical Commission or German industrial standard DIN 57530
