Abstract

The invention relates to the field of mechanical motors and discloses a two-speed motor with cooling efficiency adjusted, which comprises a motor body, a motor shaft, a rear shell, a second motor and fan blades, wherein the output shaft of the second motor is provided with a ratchet mechanism; the ratchet mechanism is arranged at the outer side of the second motor; the outer side of the second motor is provided with a connection rod; the top end of the connection rod is provided with a connection part; the connection part is internally provided with a first metal roller and a second metal roller; and the inner wall of the rear shell is provided with a first annular groove and a second annular groove. When the temperature of the motor is over high, the cooling efficiency of driving the fan blades by the motor shaft is not enough or the motor can not rotate and cooling fails in the case of a sudden condition, the second motor can drive the fan blades to rotate, the cooling efficiency is improved or the motor is independently cooled; and in a condition in which the motor shaft provides a certain rotation speed for the fan blades, the second motor drives the fan blades to rotate and energy consumption can be saved.

Description

technical field [0001] The invention relates to the field of mechanical motors, in particular to a two-speed motor with adjustable cooling efficiency. Background technique [0002] At present, in recent years, with the continuous development of the motor industry, motor manufacturers continue to pursue small size and high power density. More and more materials with high electromagnetic load and thermal load are used in motor design, and the loss generated during motor operation increases. If the overall temperature rise of the motor is too high or the local temperature rise is too high, it will not only reduce the service life of the motor, affect the efficiency, torque and other economic and technical indicators of the motor, but also cause serious deformation of the structural components of the motor, endangering the safety of the motor. [0003] When the existing motor dissipates heat, the fan blades are usually installed on the motor shaft, and when the motor shaft rotat...
