The paper presents closed-loop ac drive with 5-phase induction motor operating with voltage source inverter and sine-wave filter. The motor supply voltages and currents have sinusoidal shape. For well known adjustable electric drives the field oriented control method with flux and speed control can be applied. In the presence of output filter both control and estimation algorithms should be modified due to sine-wave filter installation. The major advantage of the drive with speed observer is an operation without motor speed sensor based on inverter currents and voltage embedded sensors. In this paper sensorless operation of a five-phase induction motor drive with inverter output filter is accomplished. The validation of the drive operation was proved by simulation and experiments. The test bench was developed with prototype of 5-phase 4.3 kW induction motor and inverter with DSP control and sine-wave filter is designed and built. © 2014 IEEE.
