High Efficiency High Torque Motor Variable Frequency Speed Regulating

Variable frequency speed regulating three-phase asynchronous motor

A. Overview

1. High efficiency and significant energy saving.
2. Smooth speed regulation can be stepless speed regulation in the range of 5-100Hz.
3. The torque impacts the load when starting at low frequency.
4, small starting current, no additional starting equipment.
5. Small size, light weight, same installation size as Y series.
6. An axial fan is installed in the hood, which has good cooling effect at various speeds.
7. It has a wide range of applications. It can be used for constant torque operation below 50Hz, and can be used for constant power operation above 50Hz.
8. Compared with electromagnetic speed regulating motor, it has simple structure, reliable use and convenient maintenance.

B. Conditions of use

1.Ambient temperature does not exceed -15 ° C ~ + 40 ° C
2.Altitude does not exceed 1000m
3.Motor protection class IP44
4. Power supply voltage 380 (220) V ± 10% Frequency 50 (60) Hz ± 2%

C. Main performance index

1. Frequency modulation range: 5 ~ 50H constant torque 50 ~ 100 constant power
2. Working system: continuous (SI)
3. Connection method: Y connection method is used for 3KW and below, but can be changed to when the inverter output is three-phase 220V, connection for 4KW and above
4. Starting torque > 125%
5. Insulation class: Class F: The maximum temperature resistance inside the motor is 110 ° C

Note: This series of variable frequency speed control motors can be equipped with encoders. The encoder's pulse and other technical parameters must be informed in advance.
