The Bosch Rexroth Indramat R911282301 (MHD115B-058-NG1-BN) is a synchronous servo motor, specifically engineered for use in industrial applications like machine tools, packaging machines, and automation. The motor is equipped to operate seamlessly with digital drive controllers, and thanks to its brushless design and a bearing that's lubricated for its entire lifespan, the motor requires zero maintenance. The MHD motors can be positioned as required, and the varied cable set designs allow for easy connection. Instant start-up is facilitated by the embedded data memory in the encoder unit. The R911282301 (MHD115B-058-NG1-BN) supports digital servo feedback. The primary motor shaft is plain and coupled with a sealing ring, and features a built-in holding brake with a 70Nm rating. Detailed technical specifics of the motor holding brake include a rated voltage of 24 Volts DC, a current rating of 1.29 Amps, and a moment of inertia of 0.003 kg m2. The brake has connection and release times of 53ms and 97ms respectively and weighs 3.8 kilograms. If used with natural convection, the motor’s rated speed is 1500 RPM, while with liquid cooling, it shoots up to 4000 RPM. With a flange size of 192mm and a centering diameter of 180mm, the motor is a flange mounted device that weighs 40 kg. Its power socket is located on side B of the housing.
