DC Marine motor,ship motor,induction motor

1. Features and Uses

Z2C series marine DC motor, The motor is suitable for the electric drive of the constant power speed range of not more than 2:1, overload capacity is not more than 1.5 times the rated torque. In order to apply a wide range of adjustment of voltage and speed at constant torque, and precise speed control, Depending on the different excitation power, the excitation voltage can be 110V, 220V, or other suitable voltages.

In addition, the Z2C series marine DC motor has also derived some other special specifications in order to meet various other special requirements:

1). Z2C special voltage motor: rated voltage is 180V, 340V, 440V, the motor is suitable for single-phase and three-phase SCR power supply. Or other places that require special voltage supplies.

2). According to special needs, Z2C series marine DC motor can also be derived with compensation windings of the motor, at this time, the overload factor can be increased to 2.5 times the rated torque. The time constant of the armature circuit can also be reduced, which is suitable for high power servo systems or occasions requiring larger overload torque.

2. Structural style

Z2C series marine DC motors basically use the structures of drip-proof single spindle extension and self-cooled fan. Apply to normal working conditions. The motor can also be made into two shafts-extension .

The basic shaft direction of the motor is the left shaft (facing the outlet box). The basic rotation directions are counterclockwise (facing the commutator).

3. Power range and Operating conditions

Power range: 0.4~200KW

  Rated voltage: 110V and 220V

    Rated speed: 3000, 1500, 1000, 750, 600 r/min

In the following conditions, this series of motors can be used continuously.

   (1)  The relative humidity of air is not more than 95%, and there is a condensation;

   (2)  The ambient air temperature is -25ºC ~ +50ºC.

In addition to the above basic voltage, speed, and special specifications derived from this catalogue, other motors with voltage and speed can also be manufactured, if necessary.

4. Excitation Mode

The basic excitation mode of motor is that the parallel connection excitation magnet with a small series-connection of stabilizing windings.

5. Starting and Driving method of motor

The motor can be driven by transmission method of elastic coupling, spur gear or triangular-belt, etc. without axial thrust. If the motor is made of two shaft-extension, the two shaft-extension of the No. 1-6 frame can transfer the rated torque, and the commutator shaft extension of of No. 7-11 frame can transfer rated torque when only there is no radial load. If there is radial load, only 50% of the rated torque can be transmitted.

If the motor power is 0.4~2KW, the motor is allowed to start with a first-class starting resistance.

If the motor power is greater than 2KW, the motor shall adopt a starter with multi-class starting resistance, or start the step by step with the reduction of the armature voltage.
