The invention discloses a sine wave subdivision driving device of a multiphase hybrid stepping motor. The device comprises a microprocessor (CPU) with an adaptive function module, an A-phase driving detection protection circuit and a B-phase driving detection protection circuit. The A-phase driving detection protection circuit comprises a driving chip IC1, a pull-up resistor R3, a current detection resistor R2, a full-control device, an inductance energy release resistor R1, a diode VD1, a hybrid stepping motor A-phase winding, a power supply VCC1, a power supply VCC2 and a ground GND. The A-phase driving detection protection circuit and the B-phase driving detection protection circuit are the same, so that other-phase driving detection protection circuits are omitted. In order to ensure that the actual current of the winding of the hybrid stepping motor conforms to the sine wave change rule, the CPU of the device is provided with a self-adaptive function module, and a sampling value table which is stored in
