For running the Induction motor via Sinusoidal pulse width modulation, what type of filter I supposed to use?

I am making SPWM inverter drive for speed control of induction motor. I got square wave at the end of the SPWM inverter. Now, how can i convert square wave into sine wave (which is neccesary to drive Induction motor). May i supposed to use a filter or suggest me other method. Thank You

There is no need to use any filter, the motor will act as a filter. PWM gate pulses are used to control the power inverter, the inverter is connected to the motor. If for learning purposes, someone may want to see that the pulse signal is actually a sinusoidal signal then a Butterworth filter can be used.
