YEJ Series
AC electric motor with totally enclosed fan-cooled (TEFC) enclosure
Our TEFC three-phase asynchronous motors (YEJ series) feature a totally enclosed fan-cooled enclosure and squirrel cage design, with an additional DC electromagnetic brake. These motors are ideal for machinery requiring rapid braking, precise positioning, and frequent start-stop operations, such as electric valves, rubber processing machines, metalworking tools, packaging machinery, woodworking equipment, food processing machines, chemical machinery, textile machinery, construction machinery, and gear reducers. They offer reliable braking, adjustable torque, and easy operation.
