Embodiment Construction

[0008] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.

[0009] Such as figure 1 As shown, the AC / DC motor of the present invention includes a frame, a front end cover 1 and a rear end cover 2; the rear end cover 2 is an open structure; the rotor shaft 4 is fixed on the frame; the inner fan blade 3 is installed on the rotor shaft 4. There are at least two inner wind blades 3 .

[0010] Due to the adoption of the open rear end cover, the invention can increase the heat dissipation effect after operation, ensure the heat dissipation capacity and heat dissipation effect of the motor, and reduce the temperature rise inside the motor. At the same time, it is convenient to replace the carbon brush and easy to use. Installing the inner fan blades 3 directly on the rotor shaft 4 can save the volume of the original fan and also r...

Abstract

The invention discloses an alternating current / direct current motor which comprises a base, a front end cover and a rear end cover. The rear end cover is of an open structure. A rotor shaft is fixed on the base. At least two inner vanes are mounted on the rotor shaft. The alternating current / direct current motor is capable of radiating effectively, low in vibration, small in size and convenient to use and maintain, and product cost is lowered.

Description

technical field [0001] The invention relates to an AC and DC motor, which belongs to the technical field of motor design. Background technique [0002] The original AC and DC motors use a fan to fix the end shaft of the motor, and add a windshield to the end of the fan. The motor rotates and the fan rotates to reduce the temperature rise of the motor. The motor is basically fully enclosed. There are following problems: the one, volume increases. The second is that it is inconvenient to replace the carbon brush or maintain the motor. The third is that after the fan is installed, the plastic is easily deformed, resulting in increased vibration of the motor. The fourth is that the cost increases. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to solve the problems mentioned in the above-mentioned background technology, and to provide an AC / DC motor that is practical and convenient, small in size, low in cost, capable of n...
