The motors can be used for various operation systems by which speed-regulation is needed, so they have wide applications in light industry, textile, chemistry, metallurgy, machine tool, etc. Fitted with highly accurate sensor, the motors can achieve highly accurate operation of closed loop.
¡¡Technical performance
¡¡ Continuous duty(s1) is applied.
¡¡ The rated voltage is 380V and the frequency is 50HZ. In accordance with user's requirement, the ratings of voltage and frequency and be also redetermined.
The insulation of motors is of Class F.
¡¡ The insulation structure has the adaptability to high carrier frequency voltage supplied by inverter.
¡¡ Speed can be adjusted in a wide range, under the condition of open loop U/f control, maintaining torque constant during 3-50HZ and output constant during 50-100HZ. And under the condition of vector control speed range can be even expanded.
¡¡ The overload capability of the motors is good, and the motors and be operated with the overload of 160% of rated torque within 1 minute.
¡¡ Motors have good performance at low speed than torque is smooth and no crawling circumstance exists.
For the type of wire-connection, motors of frame size 250 and below are of Y-connection, motors of frame size 280 and above are of ¦¤-connecition
