1、 Overview

The YEJ series electromagnetic braking three-phase asynchronous motor is suitable for spindle transmission and auxiliary transmission in various machinery, such as lifting machinery, transportation machinery, packaging machinery, food machinery, printing machinery, construction machinery, woodworking machinery, deceleration machinery, metallurgical machinery, forging machinery, etc.

2、 Model Description

3、 Introduction to Structure

This series of motors is a derivative product composed of a DC electromagnetic brake attached between the rear cover of the Y series (IP44) motor and the fan. The braking method is power-off braking. The corresponding relationship between the power level and installation size, installation size, installation type, insulation level, usage conditions, working mode, cooling method, rated voltage and rated frequency of this series of motors are the same as the corresponding specifications of the Y series (IP44). The protection level of the motor is IP44, and the mechanical part of the brake is IP23. The structure of the motor is shown in Figure 1.
