A motor speed control device

Abstract

The invention provides a motor speed regulating device, which relates to the field of motors. A motor speed regulating device, comprising a frame, a mounting part connected to the frame in rotation, a motor speed regulating mechanism and a matching mechanism, one end of the motor speed regulating mechanism is matched with the mounting part, and the end of the motor speed regulating mechanism far away from the mounting part is connected with a first The motor and the matching mechanism are slidably arranged on the frame, and the matching mechanism is optionally close to or away from the mounting part. The matching mechanism is equipped with a second motor, which is used to drive the matching mechanism to slide, and the matching mechanism is connected to the motor speed regulating mechanism. The invention can be used for speed regulation of a mechanical motor and improves the adjustment accuracy and sensitivity of the motor.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor speed regulating device. Background technique [0002] The existing digital electronic governor control theory adopts traditional PID control. For nonlinear transient systems such as diesel engines, which include gas flow, reciprocating mechanical motion, fuel injection, oil-gas mixing, combustion expansion, etc., plus Due to the complexity of the working conditions of the locomotive diesel engine, the traditional PID control is difficult to solve its nonlinear transient problem. [0003] The development of digital electronic governors in China is relatively slow, and most governors are still mechanical governors, and it is difficult to realize instantaneous and reliable engine speed regulation. Due to the large friction resistance torque of the torque motor, the steady-state characteristics are not good, which in turn affects the adjustment accuracy and sensitivity of the entire s...
