The YE3 series motors have a total of 13 frame sizes, among which the frame and end cap structural materials of H63-H112 frame sizes are made of cast iron or alloy aluminum, while H132 and above frame sizes are made of high-strength cast iron. The heat dissipation fins of the motor are distributed horizontally and vertically. The motor junction box is located at the top and side of the extension base, with two structures that have a beautiful overall appearance and are available for users to choose from. The YE3 series three-phase asynchronous motor is a fully enclosed, externally cooled, cage type structure. It has the characteristics of novel design, beautiful appearance, low noise, high efficiency and torque, good starting performance, compact structure, and easy use and maintenance. The whole machine adopts F-level insulation and is designed according to the internationally recognized insulation structure evaluation method, greatly improving the safety and reliability of the whole machine. It can be widely used in various mechanical transmission equipment such as machine tools, fans, water pumps, compressors, transportation, agriculture, food processing, etc.
