Frequency control method

Frequency control of motor speed is to change the frequency of the motor stator power,to change its synchronous speed control method.Variable frequency speed regulation system is the main electric motors price equipment to provide frequency conversion single phase induction motorpower converter.Inverter can be divided into ac-dc-ac frequency converter wholesalemotor.blogspot.com and

ac-ac frequency converter two kinds big,cross-straight-to pay inverter are mostly used in China at present.Features: high efficiency,speed the process of no additional loss;Application range is wide,can be used in the cage type asynchronous motor;Large range of speed regulation,and the characteristics of hard and high precision;Technology is complex,high cost,maintenance difficulties. This method is suitable single phase asynchronous motor for the requirement of high precision,better speed control performance.
