BPT series frequency converter

Overview

The series frequency converter is mainly used for motor drive speed regulation in industrial energy-saving automation control. It changes the control method of adjusting the flow rate by adjusting the opening of the outlet valve while the motor is always rotating at full speed. This product is widely used in metallurgy, steel, petroleum, mining, building materials, food, pharmaceuticals, textiles, chemical fibers, papermaking, water supply and central air conditioning systems.

Basic Principle

The series of variable frequency speed regulators adopt the advanced directional voltage vector control mode, that is, the magnetic field and torque do not interfere with each other, and the torque is controlled according to the instructions. Through / control switching, adjust the control power frequency to change the motor speed, achieving smooth running and high-torque, high-precision speed and torque control at extremely low speeds.

Performance characteristics

Suitable for smooth starting and speed regulation of squirrel cage motors
Good speed regulation smoothness, speed regulation range can be reached
Has Torque boost function, automatically compensates for insufficient torque when the speed is low
With soft start function
Pause acceleration and deceleration function (stall protection)
Intelligent fault diagnosis system, with overvoltage, undervoltage, Overheating, current limiting and other protection functions.
