Description

Technical Field

[0001] This utility model belongs to the field of motor technology and relates to an electromagnetic high-speed braking device for a three-phase asynchronous motor. Background Technology

[0002] Three-phase asynchronous motors are a type of induction motor that are powered by three-phase AC current connected to the same source (380V). Because the rotor and stator rotating magnetic fields of a three-phase asynchronous motor rotate in the same direction but at different speeds, there is slip, hence the name three-phase asynchronous motor.

[0003] A controller is installed on a three-phase asynchronous motor. The controller is an electromagnetic brake controller, which is directly installed on the motor housing. During use, the motor generates a lot of heat. Traditional motors dissipate heat through a metal housing. When the heat dissipation space is small or the external temperature is high, the heat dissipation effect may be poor, which will affect the controller. Therefore, an electromagnetic brake device for motors is proposed to address the above problems. Summary of the Invention

The controller 16 is a publicly available electromagnetic braking controller, which will not be described in detail here.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the electromagnetic high-speed braking device for a three-phase asynchronous motor of this utility model has a fixed plate 10 at one end of the supporting side plate 7. The outer side of the fixed plate 10 is threaded with a locking bolt. A locking hole is opened on the side of the outer shell 2, and one end of the locking bolt is threaded into the inside of the locking hole.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the electromagnetic high-speed braking device for a three-phase asynchronous motor of this utility model has a traction groove 13 inside the mounting base 11. A lead screw 14 is movably installed inside the traction groove 13, and one end of the lead screw 14 is connected to the turntable 15 at the end of the mounting base 11. A traction slide 19 is provided at the bottom of the heat dissipation cover 3.
