Ac motor power frequency conversion
One, ac motor power supply Ac motor generally adopts three-phase system, compared with the single phase motor, because of the three-phase ac motor in both the performance index, the use of raw materials and price, etc, has the obvious superiority. The three-phase motor of the same power is small, light and low in price. Three-phase motor has self-starter capability. Single phase motor has no torque, and special measures are needed to solve the starting problem. The torque of single phase motor is pulsed and noisy
The output frequency is the maximum 600Hz, which can control high-speed motor The all-around detection protection function (overpressure, undervoltage, overload) is instantaneous without power Noil accelerates, decelerates, and loses speed to prevent the protection function The dynamic parameter automatic identification of the noil motor ensures the stability and precision of the system The response is fast when the noil is down fast It has abundant and flexible input, output interface and control mode It adopts SMT full-stick production and three anti-coating process, the product is stable and high The whole series adopts the latest Siemens IGBT power device to ensure the quality of quality
Ac motor variable frequency control Inverter is the application of frequency conversion technology and microelectronic technology, by changing the frequency and amplitude of motor power to control ac motor power transmission components. The characteristics of ac motor speed converter: the low-frequency torque output 180%, the low-frequency running characteristics are good
