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.

Ordering Informations

1.Please indicate the motor type,rated output,rated voltage,rated frequency,synchronous speed,Explosion proof Mark,mounting type,rotation direction(view from the shaft extension side)Use of the environment(indoor or outside)If the user havn't point out the rotation and environment,normailly we think is CW roration and used indoor.

2.when user have special requirments,For example:Dispose the stator,bearing explosion proof and bearing temperature sensors,space heater,Plateau use,specical frequency,mounting size change,special output,the user must ,order can be confirm after signing the technical agreement with engneering department .
