Description

technical field

[0001] The invention relates to the technical field of motors, in particular to a treadmill motor. Background technique

[0002] Treadmill is a common equipment for home and gym, and it is the simplest type of home fitness equipment today, and it is the best choice for home fitness equipment. The treadmill motor (hereinafter referred to as the motor) is the power source of the treadmill. Because the motor is used in a relatively sealed space, the heat dissipation of the motor is very important. Most of the end covers of the prior art motors are closed, and although a small part has ventilation holes, these ventilation holes cannot form a good air duct, so that the heat on the windings cannot be well dissipated. take away, and the air flow that can be driven by the rotor of the prior art is small when it rotates, so that the winding can not be well radiated heat, resulting in poor heat dissipation effect of the whole motor; and the motor of the prior art is...
