The present invention can provide a motor including a shaft, a rotor coupled to the shaft, a stator disposed to correspond to the rotor, and a control unit electrically connected to the stator, wherein the control unit includes a substrate and an element having a lead disposed on the substrate, the lead of the element is coupled to the substrate using a solder and includes an end exposed from the solder, and the solder is spaced apart from the end of the lead.

Equipment for welding a motor stator to a substrate includes a protective hood and a hot pressing head. The protective hood covers the motor stator and the substrate to protect the motor stator from undesired displacing and possible damage, and is provided with a plurality of wire slots, via which lead-out wires of coil windings of the motor stator can be pulled out to expose from the protective hood. The hot pressing head has a hot pressing end corresponding to welding points on the substrate and is movable to cover an outer side of the protective hood while the hot pressing end heats and welds the lead-out wires and the welding points together. With the equipment, all the coil windings of the motor stator can be welded to the substrate in one single movement while the motor stator is protected against splattered solders during the welding operation.

A method for welding a motor stator to a substrate includes steps of: providing a motor stator and a substrate; preliminarily fixing the motor stator to the substrate; pulling out lead-out wires of coil windings wound on the motor stator to align with solders of welding points on the substrate; covering a protective hood on the motor stator; covering the hot pressing head around the protective hood while the hot pressing end is located corresponding to the welding points; heating and compressing the welding points to melt the solders; and waiting the molten solders on the welding points to cool and cure to weld the coil windings of the motor stator to the welding points. With the present invention, all the coil windings of the motor stator can be welded to the substrate in one single movement while the motor stator is protected against splattered solders during the welding operation.
