The Working System Of The Motor

The load conditions of the motor include start-up, electric braking, no-load, power failure and stoppage, as well as the duration and sequence of these stages. The working system is divided into the following 9 categories:

S1. Continuous duty:

The operating time under constant load is sufficient to achieve thermal stability.

S2. Short-time working system:

Run for a given time under constant load, the time is not enough to achieve thermal stability, and then the power is cut off and stopped for a sufficient time, so that the motor is cooled again to the temperature difference with the cooling medium within 2K.

S3. Intermittent cycle work system:

Operate according to a series of identical work cycles, each cycle includes a period of constant load running time and a period of power-off stop time. The starting current of each cycle in this duty system will not have a significant effect on the temperature rise.

S4. Intermittent cycle working system including starting:

Run according to a series of identical working cycles, each cycle includes a starting time that has a significant impact on temperature rise, a constant load running time and a power-off stop time.

S5. Intermittent cycle working system including electric braking:

Operate according to a series of identical working cycles, each cycle includes a period of starting time, a period of constant load operation, a period of fast electric braking time and a period of power-off stop time.

S6.Continuous cycle work system:

Run according to a series of identical work cycles, each cycle includes a period of constant load operation time and a period of no-load operation time, but there is no time for power off and stop.

S7. Continuous cycle working system including electric braking:

Run according to a series of identical working cycles, each cycle includes a period of starting time, a period of constant load running time and a period of fast electric braking time, but there is no time to stop the power off.

S8. Continuous cycle duty system including variable speed and variable load:
