It is a 3 phase syncronous motor, modulated by the inverter based on control from the HV ECU. The frequency is relative to the desired speed of the compressor. MG1 and MG2 work the same way, except they operate at a nominal 500V.
The speed it is set to is determined by cooling or dehumidifying demand as determined by the Air Conditioning ECU (also known as AC Amplifier). Inputs include cabin temp, cabin humidity, outside temp, solar radiation detected, and your desired feels like temp.
