Abstract

The invention discloses a single-phase series motor with good heat dissipation performance, and relates to the technical field of series motors. The single-phase series motor comprises a cavity seat and a motor shell arranged above the cavity seat, an air cooling mechanism is arranged in the motor shell, a water cooling mechanism is arranged on one side, opposite to the cavity seat, of the motor shell, the interior of the cavity seat is filled with cooling liquid, and an inner support is fixedly installed on the inner wall of one end of the motor shell. An air cooling assembly is arranged, the motor run to enable a shaft rod to rotate and drive a fan blade assembly to rotate, so that an air inducing effect is achieved, external air enters an exhaust pipe through a filter screen through cover and then is blown out through an air inlet ring pipe and arc-shaped air outlet branch pipes, air blowing into the motor is achieved, and an air cooling effect is achieved; and on the other hand, the plurality of arc-shaped air outlet branch pipes are annularly distributed at equal intervals, so that the blown air can generate cyclones, and the cold air is in full contact with internal components of the motor.

Description

technical field [0001] The invention relates to the technical field of series-excited motors, in particular to a single-phase series-excited motor with good heat dissipation. Background technique [0002] Single-phase series-excited motors, commonly known as series-excited motors or general-purpose motors, get their name because the field winding and the field winding work in series. Single-phase series motors are AC and DC dual-purpose motors, which can work with either AC power or DC power. Series motors are widely used in the fields of power tools, kitchen supplies, and floor care products due to their wide range of adjustable speed and large starting torque. Single-phase series motor has high speed, light weight and convenient speed regulation, so it is used as the power source in most electric tools. However, the single-phase series motors used in electric tools start frequently, have high speed, large vibration, uneven load, and are easy to stall, which makes the arm...
