The Mitsubishi MELSERVO-J4 TM-RFM High-Rigidity Series Direct Drive Motor is built around a magnetic synchronous motor, with a space-saving design that eliminates traditional mechanical transmission components. Direct load control paired with servo motor accuracy is compactly packaged with simplified installation via the hollow flanged shaft. The TM-RFM High-Rigidity Series is built to operate at rated speeds of up to 200rpm, with a maximum of 500rpm. Rated output is from 42 to 2513W, with torque from 2 to 240Nm(dependent on model.)

The TM-RFM High-Rigidity Series is equipped with a 20-bit absolute feedback encoder, which can deliver up to 1,048,576 pulses per revolution. This product line is built to handle low-speed and high-torque operations, an ideal solution for applications requiring robust and reliable rotary motion for high-load tasks.
