YZR, YZ Series Hoisting Motor And Crane Motor

YZR and YZ series winding rotor and squirrel cage rotor three-phase asynchronous hoist motors are for hoisting and metallurgical machines and other similar equipment. With great load capacity and mechanical strength, they are suitable for equipment with short time or intermittent duty, frequency start or brake, obvious shock and impact. YZR series motors are of wound rotors type, while YZ series motors are of squirrel cage type.

The standard range of power output and mounting dimensions are in comply with the recommended standard of IEC 72. The relation between range of power output and mounting dimensions are similar to Japanese standard JEMI202 and Germany standard DIN42681, so that most of them can be interchanged.

YZR, YZ Series Hoisting Motor And Crane Motor Working Duty: S2,S3,S4,S5

1.Short-time duty type (S2)

Operation of constant load during a given time, less than that required to reach thermal equilibrium, followed by a rest and de-energized period of sufficient duration to re-establish machine temperature within 2 deg K of the coolant.

2. Intermittent periodic duty type (S3)

A sequence of identical duty cycles, each including a period of operation at constant load and a rest and de-energized period but the operation period are so short that it is not sufficient for the machine to reach thermal equilibrium In this duty type, the cycle is such that the starting current does not significantly affect the temperature rise.

3. Intermittent periodic duty type with starting (S4)

A sequence of identical duty cycles, each including a significant period of starting, a period of operation of constant load and a rest and de-energized period, but the operation period are so short that it is not sufficient for the machine to reach thermal equilibrium.

4. Intermittent periodic duty type with electric braking (S5)

A sequence of identical duty cycles, each consisting of a period of starting, a period of operation at constant load and a rest and de-energized period, but the operation period are so short that it is not sufficient for the machine to reach thermal equilibrium.
