YZP series metallurgical and reuse frequency conversion speed regulation three-phase asynchronous motor is a speed regulation three-phase asynchronous motor with frequency conversion speed regulation device as the power supply, and the system composed of frequency conversion device can achieve stepless speed change; Achieve the purpose of energy saving and control automation. Because of the characteristics of high efficiency, wide speed range, good precision, stable starting and braking operation, and large overload capacity, especially suitable for frequency conversion speed regulation, short or intermittent cycle operation, frequent starting and braking occasions.

      The basic technical requirements of the motor meet the requirements of IEC34-1 and GB755 standards, and the installation dimensions meet the IEC71 international standards. The motor can be equipped with thermal protector, heater, encoder, electromagnetic brake, overspeed switch, speed generator and other additional devices to meet the requirements of users.

Motor is suitable for intermittent periodic working system. According to the different nature of load, motor working system can be divided into:

1. Short-time working system (S2) : operate at a constant load for a given time. When the motor does not reach the thermal stability state, it will stop and cut off energy for a period of time, so that the temperature difference between the motor and the cooling medium is within 2K.

Duty periodic 

2. (S3) : according to a series of the same work cycle run, each cycle by a constant load running time and period of downtime and can break time, but the time is shorter, are not enough to make the motor to achieve thermal stability state, and each cycle of the starting current had no obvious effect on temperature rise.

3. Intermittent periodic working system including starting (S4) : according to a series of the same working cycle, each cycle consists of a period of starting time, a period of constant load running time, a period of shutdown and power outage time; However, these short times are not enough to achieve thermal stability of the motor.

4. Intermittent periodic working system including electric braking (S5) : according to a series of the same working cycle, each cycle is composed of a period of starting time, a period of constant load running time, a period of downtime and outage time; However, these short times are not enough to achieve thermal stability of the motor.
