China variable frequency drive - VFD, AC drive inverter, frequency converter and AC power source manufacturers.

Sensorless AC inverter

sensorless ac inverter
Overview: It enables high torque in very low frequency and adopt special 32 bit high CPU to control AC motor speed smoothly. The inverter can continuous running in instantaneous power off and detect motor speed in real time, this advantages allow the users easily conduct bulk inverters in the working area with unstable power supply environment, and make the motor working smoothly running from its current speed with no impact.
