Rexroth Indramat MHD motors are permanent magnet synchronous motors with electronic communication. MHD motors are available in a wide range of configurations that include specifications like motor feedback, cooling method, holding brake and output shaft. Considered a legacy motor, Indramat MHD motors are still found in service today in applications like printing, packaging, and textiles. These motors are fully sealed and maintenance free, containing lubricated bearings that last the lifetime of the motor. MHD motors come in 8 frame sizes: 041, 071, 090, 093, 095, 112, 115 and 131.
