Product Detail

WSTK Series Motors are permanent magnet synchronous motors, specially designed for air compressor industry. Compact in size, the product has heavy starting torque, strong overload capability, no slip and can be precisely controlled without encoder control. Without rotor loss, WSTK is able to run at higher efficiency and achieve IE4 super premium efficiency or even above.

High performance NdFeB magnet and high quality stamping: the rotor is produced using high performance RE permanent magnet materials.

Axial flow fan: inner rotor structure, longer life under high temperature environment than outer rotor motor.

SKF bearing: grease with different degrees of heat resistance can be applied for various applications.

Oil injection device: extended tube adopted for oil injection without removing the fan cover.

Advanced inverter to achieve premium energy saving and precise speed control.

WSTK Series also have the technical advantages of small frame, high power density, high torque density, low noise level, etc.

The inverters supplied to WSTK Series have outstanding performance, including high torque, fast response, high accuracy and excellent environmental compatibility with easy operation. They are designed for controlling wide range of variable torque and constant torque applications such as pumps, fans and control in various types of industries.
