On March 14, 2017, WPG Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market , announced that its subsidiary WPG launched a motor drive reference solution based on the Toshiba product line, including a three-phase brushless sensorless motor drive solution , a three-phase full-wave sine PWM drive solution , a motor drive control solution , and a three-phase motor drive solution .
A motor is an electromagnetic mechanical device that uses the interaction between electricity and magnetism to achieve energy conversion and transmission. From small household appliances such as fans, washing machines, refrigerators and air conditioners to large office equipment, electric vehicles, automobiles, industrial applications, etc., it can be said that motors are needed almost anywhere that needs to provide power.
