Embodiment Construction

[0009] see Figure 1-3 , The built-in multi-disc brake permanent magnet motor disclosed in the present invention includes a rotor 220, a stator and a built-in brake device, the rotor is located in the stator and is connected to the stator through a bearing for rotation, and the iron core of the stator 120 is installed in the casing 110 of the motor. The casing is provided with a front end cover 112 and a rear end cover 113. The rotating shaft 210 of the rotor faces forward and extends from the shaft hole of the front end cover to form the output of the motor. The shaft is usually equipped with an output gear 212, and the rear part of the rotor is a cylindrical section with an open rear end, which is provided with a cylindrical space 221 capable of accommodating the built-in multi-disc braking device. The moving device includes a rotating cylinder 311, a brake cylinder 321, a brake disc assembly 330, an elastic device and a power device 350. The brake disc 331 and the static b...

Abstract

The invention relates to a built-in multi-disc brake permanent magnet motor, the rear part of the rotor is built with a multi-disc brake device, and the multi-disk brake device includes a rotating cylinder, a brake cylinder, a combination of brake discs and an elastic device and the power device, the dynamic brake discs and static brake discs in the brake disc combination are distributed alternately, the dynamic brake discs are axially and movably connected to the rotating cylinder, and the static brake discs are connected to the brake discs The moving cylinder moves axially, the elastic device is located at the rear side of the brake disc assembly, and a spring / spring combination is provided to push forward the brake disc located at the rearmost side, and the rotating cylinder is fixedly installed On the inner wall of the cylindrical section at the rear of the rotor or directly using the cylindrical section at the rear of the rotor, the rear end of the base body of the power device is fixedly connected to the rear end cover. The invention has a braking function, and when used in equipment such as a crane, it can significantly simplify the structure of the whole machine, reduce the overall volume, and reduce manufacturing costs and operating expenses.

Description

technical field [0001] The invention relates to a built-in multi-disk brake permanent magnet motor. Background technique [0002] Due to the wide speed range of the existing permanent magnet motor, it is allowed to run at a lower speed. When used in cranes and other equipment, the requirements for the reducer can be significantly reduced, and the reducer can be simplified or even eliminated. The magneto does not have a built-in brake device. When used in cranes and other equipment, an independent brake device needs to be installed separately. The commonly used brake device is a caliper brake device, which is installed on one side of the drum. The caliper grips the brake flange or disc for braking. In order to achieve this braking, the diameter of the brake flange is often large, and the installation of the caliper brake device needs to occupy a large space, especially in the radial direction of the drum, which severely limits The application of permanent magnet motors in c...
