Durable High Torque Electric Motor Generator Asynchronous Motor 3 Phase

 Torque motor controller series electromagnetic brake three-phase asynchronous motor

This controller is an advanced fully electronic control device specially designed to replace the three-phase autotransformer and can work in resistive and inductive load states. Widely used in hardware machinery, plastic film, wire and cable, rope net, printing, papermaking, chemical fiber textile printing and dyeing, rubber and other mechanical and electrical industries. Compared with three-phase auto-coupling voltage regulator, this controller has good starting performance due to its electronic regulation, no contact wear, balanced voltage regulation. The controller has the characteristics of small volume, light weight, high efficiency, low heat generation, energy conservation, long service life, convenient installation and maintenance, etc.

 

II. Working Conditions:
1. Ambient temperature:-25℃ ~+50℃.
2. Air relative humidity: ≤ 85% (20℃ 5℃).
3, no significant impact vibration.
4. Operating voltage: 3-phase 380 V (10%). In addition to this standard design, special voltage designs (such as 220V, 400V, 415V, 440V) can also be provided for users.
5. Operating frequency: 50 ~ 60Hz.

Three, working principle:
The main circuit of the controller adopts imported bidirectional thyristor, and the thyristor control circuit adopts a three-phase coaxial control potentiometer to synchronously adjust the conduction angle of the three-phase thyristor, so that the working voltage of the load can be continuously adjusted from 0 to 375 V, thus realizing a balanced voltage regulation and speed regulation process and meeting the requirements of different production processes. Due to the unique circuit design, the damage of the motor can be effectively avoided.
