Accept OEM ODM AC Motor Constant Torque Inverter Variable Frequency AC Motor

Product Description

Variable Frequency Motor Introduction

Variable frequency motor is dedicated to matching frequency converters for stepless speed control. It saves 10%-30% more energy than fixed-speed motors under variable load, with lower operation noise and temperature rise.
Equipped with IP55 protection and TEFC cooling structure, it withstands frequent start-stop and reverse rotation for long-term stable operation. It can directly replace ordinary motors without mechanical modification, widely applied to fans, pumps, compressors and automation equipment to cut energy consumption and operating costs.
