External force tracking ratchet motor

Abstract

This invention provides a device that allows for torque adjustment using a brushless DC motor. [Solution] The stator is fitted with bearings, a rotor position sensor, a rotor, a ratchet gear, a fixed shaft, a ratchet pawl, a solenoid, and a spring. The torque motor has a ratchet rotating part, which is locked by the ratchet locking part and rotates in one direction. The controller controls the torque motor and solenoid to control the external force. A PC torque setting device and a sound unit are connected to the controller to adjust the amount of torque drawn.

Description

Technical Field

[0001] In order to increase the stopping load of a brushless DC motor, it is necessary to rotate it in the reverse direction in proportion to the external force. However, if the external force suddenly decreases, it will rotate rapidly and enter a dangerous state. Also, it is necessary to apply a certain stopping torque during stopping. Therefore, by providing a mechanical and electrical ratchet mechanism to rotate the motor in a certain direction, the stopping torque can be increased. Technical background

[0002] In a roll material anti-reflection, muscle tremor machine, and rehabilitation equipment, when using a brushless DC motor to increase the reaction force and braking torque, the motor is applied with a reverse torque, and if necessary, the reverse torque is loosened, the accelerator is depressed by a certain amount, held by the brake, and the brake is loosened to adjust the rotation amount.

Summary of the Invention

[0003] The torque of a brushless DC motor increases in proportion to the rotational speed. By controlling the motor to the reverse rotation side and mechanically and electrically suppressing the reverse rotation, when the external force exceeds the reverse torque, it can rotate forward at a constant speed, and the motor can be used as a brake. Means for Solving the Problems

[0004] In a brushless DC motor, a certain magnetic force (set torque) is applied in the reverse direction, and the rotation is mechanically and electrically stopped. When the external force exceeds the set torque, it rotates forward in a form pulled by the external force. Effects of the Invention

[0005] By providing a ratchet mechanism in a brushless DC motor, it can be used as a powerful braking device. The ratchet can be released to perform winding. Since the external force following torque can be increased, it can be used as a muscle strength training device.
