The working frequency of high-speed motor (electric spindle) is usually several hundred hertz or several thousand hertz. The frequency of our ordinary industrial power is 50/60Hz, so we need to use high-frequency controllers (drivers, frequency converters) to increase the frequency of the output to the motor, control the motor parameters, and make the motor operate according to our expected goals according to the relevant sensors and control logic.
The performance of high-frequency inverter, such as the stability of output voltage, temperature rise, etc., will affect the operation status and life of high-speed motor. Especially, the driver of high speed and high power permanent magnet synchronous motor is often equipped with reactor, power protection module, etc. At the same time, it is necessary to adjust the parameters of the driver in the whole speed range of the synchronous motor to ensure that the motor and driver operate in the best state. Poor performance of the driver or inexperienced commissioning personnel may cause damage to the synchronous motor or driver.
ACOMEL of Switzerland used to belong to Kollmorgen, Danaher and Warner groups respectively. Therefore, in the market, Acomel, Kollmorgen, Danaher, Warner and other brands of high-frequency converters are all from one company. The highest output frequency of Acomel can reach 5000Hz (ACO5000 series), the input voltage is 0-480V, and the output voltage is between 0 and the input voltage, either single-phase or three-phase. Acomel frequency converter is equipped with selective harmonic suppression (SHS) function, which can well control high-speed asynchronous motor without filter and reactor
Shanghai Aixin Drive provides parameter setting, testing, maintenance, upgrading and other technical services for ACOMEL inverter.
KOBE (KEB) is a famous supplier of high-frequency converters in Germany. Its frequency is usually up to 1600Hz, and can be upgraded to 3000Hz if necessary. KEB frequency converter can drive synchronous motor and asynchronous motor. It can be controlled in closed loop or open loop. It can also realize closed loop control for permanent magnet synchronous motor without motor encoder. KEB high-frequency inverter is widely used in machine tools, fans, elevators and other high speed fields.
We can provide the sales, maintenance and other technical services of the original high-frequency inverter of KEB.
