Description

A treadmill drives a DC brushless motor

technical field

The utility model relates to the technical field of motors, in particular to a brushless DC motor driven by a treadmill.

Background technique

Most of the existing treadmill motors are installed independently, and the kinetic energy is transmitted to the motion mechanism through a belt drive. The motor takes up a lot of space, causing the treadmill to be bulky and difficult to fit in a small space. For example, the published patent No. ZL201210530220.6 is the "treadmill motor". The motor of this technology can only be installed independently and must occupy a corresponding space, which brings difficulties to the compact design of the treadmill.

Existing treadmill motors are also mostly AC motors or brushed DC motors. Due to its inherent performance, AC motors have problems such as large size, poor low-speed performance, difficult control, and low efficiency; brushed DC motors have disadvantages such as low reliability and high failure rate due to their carbon brush contact structure.

The utility model adopts the following technical solutions to solve the above-mentioned technical problems:

A brushless direct current motor driven by a treadmill comprises a motor body and a controller connected by several wires, and the controller is installed at any appropriate position of the treadmill.

The motor body includes a body, a motor shaft, a right end cover, a left end cover, a right bearing, a left bearing, a permanent magnet block, and a stator assembly. The right end cover and the left end cover are consolidated with the body; the right end cover, The left end cover is respectively consolidated with the right bearing outer ring and the left bearing outer ring; the body is consolidated with the permanent magnet block through a magnetic steel frame; the motor shaft passes through the stator assembly and After solidification, the left end passes through the inner ring of the left bearing and is consolidated, and passes through the left end cover at the same time, and the right end passes through the inner ring of the right bearing and is consolidated, and passes through the right end cover at the same time; the stator assembly A positioning sleeve is installed between the inner ring of the right bearing; the stator assembly corresponds to the permanent magnet block.

The two left and right ends of the motor shaft are fixed on the treadmill frame, and the body rotates around the motor shaft, that is, the outer rotor type.

The body is directly used as the driving wheel of the running belt of the treadmill to realize the integration of the motor and the driving wheel of the running belt, does not occupy space, and has a very compact volume.

Several wires drawn out from the stator assembly pass through the side hole of the positioning sleeve and the shaft guide hole, are drawn out from the right end of the motor shaft, and connect with the controller.

The utility model has the beneficial effects that: the motor is integrated with the driving wheel of the sports belt, does not occupy space, and the volume is very compact, which provides conditions for the compact design of the treadmill; because the DC brushless motor is used, it can play the role of the DC brushless motor. Good control performance, large starting torque, wide speed range, good low-speed performance, stable operation, good reliability, high efficiency, energy saving and other characteristics improve the performance of the treadmill.
