To provide a motor drive controller for hybrid vehicle, capable of concurrently achieving output characteristics of a motor within an operating range in assisting vehicle drive and output characteristics of the motor in starting an internal combustion engine, in spite of a simple and low-cost configuration, thus achieving good output characteristics of the motor in starting and within a wide operating range.

The motor drive controller for hybrid vehicle, which is a drive controller of a motor 2 for a hybrid vehicle with an internal combustion engine 1 and the motor 2 as a drive source, switches connecting states of field windings 2C1-2C3, 2C4-2C6, 2C7-2C9 of a plurality of motors 2 provided for each phase (U-phase, V-phase, W-phase) between serial connection and parallel connection according to operating states.
