3.Main features and application of the Three phase ac inverter.
High starting torque at low speed: in the mode of closed-loop control,speed control, slip compensation,torque compensation, the series inverter can realize 150% rated torque at the zero speed . Application:CNC machine, crane, lift,winding machine,cement machine, mine conveyor In the field of air conditioning, use the "custom logic function" calculation function provided by the inverter. No external circuit composed of simple PLCs, relays, and timers is required.

Low speed operation
Most induction motors can operate with modern Frequency inverters through moderate speed ranges (around 30% to 100% speed). Sustained operation at low speeds and, in particular, high load at low speeds may require a special or larger drive and special measures to cool the motor.
AC induction motors operate hotter with a Frequency inverter because of harmonics, impurities in the electric power they provide to the motor and also the slower rotating speed of the motor's integral cooling fans. This is usually not a problem if speeds are continuously above 40% or where there are brief periods of slow-speed operation. However, prolonged operation at or below about 30% speed, especially when driving significant loads, can cause rapid and potentially damaging heat in some motors.
