Fitness equipment driving device based on magnetic encoder and control method thereof

Abstract

The invention discloses a fitness equipment driving device based on a magnetic encoder and a control method thereof. The driving device comprises a controller and a three-phase direct-current brushless motor, the three-phase direct-current brushless motor is arranged on a moving arm of fitness equipment, the magnetic encoder is arranged on the three-phase direct-current brushless motor, the controller performs electronic commutation by collecting signals of the magnetic encoder to control the steering of the motor, and outputs PWM voltage signals to control the rotating speed of the motor; the controller obtains the absolute position of the motor through the magnetic encoder. According to the fitness equipment driving device based on the magnetic encoder and the control method of the fitness equipment driving device, the three-phase brushless direct current motor is adopted to replace a traditional mechanical power device, the position of a moving part is accurately monitored in real time through the magnetic encoder, speed control and torque adjustment are conveniently carried out, and the user experience is greatly improved.

Description

technical field [0001] The invention relates to a fitness equipment and a control method thereof, in particular to a magnetic encoder-based fitness equipment driving device and a control method thereof. Background technique [0002] Fitness equipment is often divided into two categories: single-function and comprehensive multi-function according to the number of training functions. , Commonly used single-function equipment includes rowing machines, fitness bikes, walking machines, treadmills, waist shaping machines, etc. Their main functions are: Increase Arm Strength: Dumbbell Grip Multifunctional Sit Up Board. For example, treadmills are mainly used to exercise legs, hips, waist, abdominal muscles and cardiopulmonary function, and rowing machines are mainly used to enhance arm strength, latissimus dorsi and movement coordination. [0003] Comprehensive multifunctional machine: generally includes the functions of chest expanders, pull-ups, supine presses, sit-ups and othe...

AI Technical Summary

Problems solved by technology

[0004] Fitness equipment will use stretching or pushing power devices. The existing power devices generally use mechanical power devices. The torque and speed control is relatively rigid, difficult to adjust and display in real time, and the user experience is poor.
