The embodiment of the invention discloses a load speed regulation conversion control method based on a limited angle torque motor, and relates to the technical field of automatic control. The method comprises the following steps: receiving a hoisting instruction; measuring the hoisting tension at the current moment through a pressure sensor mounted at the hoisting hook; determining a target duty ratio of a PWM wave according to the hoisting tension; and inputting PWM waves with the duty ratio being the target duty ratio into a limited angle torque motor for hoisting so as to regulate the speed of the limited angle torque motor. According to the invention, the input duty ratio of the limited angle torque motor can be automatically adjusted according to the collected hoisting tension, so that a load can be rapidly hoisted, the hoisting working efficiency is improved, and the service life of equipment is prolonged.
