Problems solved by technology
[0002] The treadmill motors currently on the market are all permanent magnet DC motors with carbon brushes. The carbon brushes have the disadvantages of short service life and low motor output efficiency, and the commutation is prone to sparks, which will interfere with the power grid. The active rollers of the treadmill running belt are all driven by multiple belts. There are many parts used, and energy is easily lost in the middle. The cost is high and the space is large.
[0003] The brushless motors on the market now require motors with Hall sensors to identify the spatial position of the motor rotor, but the installation of Hall sensors increases the difficulty of the production process of DC brushless motors

The invention discloses a treadmill DC brushless roller motor, which is characterized by comprising a mandrel, a roller, a bearing, an end cover, a permanent magnet, a coil winding and a driver, wherein the roller is an active roller of a treadmill running belt; the coil winding is fixedly connected to the outer side surface of the mandrel; ten permanent magnetic tiles with rare earth added form acircle to form the permanent magnet, the permanent magnet sleeves the coil winding and is fixedly connected to the inner side surface of the roller; the power leading-out wire of the coil winding isled out by one end of the mandrel; and the power leading-out wire of the coil winding is connected with the driver. The treadmill DC brushless roller motor has the beneficial effects that the roller and the motor are adopted as one, a multi-conducting belt transmission structure is eliminated, the energy loss is reduced, the cost is reduced, a hall sensor is cancelled, the production process difficulty of the motor is reduced, the service life and the stability of the motor are improved, and by adopting the form of stacking of multiple coil windings, high power and high torque are realized when the size is small.
