The invention discloses a motor no-decelerating energy-saving inversion control system based on an amplification drive circuit. The system is formed by a rectifying circuit, a central controller module, an RC filter, a DC voltage detection module, a motor, a DC current detection module, an SPW module, a voltage output detection module, a signal input interface, a keyboard, an ROM module, a panel indication module, an NVRAM module, and a thyristor controllable inverter circuit. The motor no-decelerating energy-saving inversion control system is characterized in that the amplification drive circuit is connected in series between the thyristor controllable inverter circuit and the motor. The amplification drive circuit is utilized, and the circuit can effectively amplifies the current output by the thyristor controllable inverter circuit, and can effectively drive the motor to run, so that the motor does not need decelerated running any longer when load needs to be reduced.
