The Bosch R911282443 (MHD112D-027-PG0-BN) is a Rexroth MHD series synchronous motor with a 112 frame size, D frame length, and 027 motor winding code. It includes a built-in multiturn absolute encoder for digital servo feedback and a plain shaft with a sealing ring. While it doesn't come with a holding brake, one can be separately ordered if needed. Electrical power is connected on side B, and the motor housing facilitates cooling through natural convection. Characteristic attributes of this motor consist of a 3000 RPM speed, 142.2 Amp peak current, 5.65 mH winding inductivity, and 0.35 Ohms winding resistance. It also features a maximum 187 Nm torque, 350 x 10-4 kg m2 rotor inertia, and IP65 housing rating. The R911282443 (MHD112D-027-PG0-BN) weighs 56 kg and should be stored at temperatures between -4°F and 176°F if unused. It operates best in temperatures of 32 to 104 degrees Fahrenheit and below 1000 m above sea level. Commissioning and maintenance of this motor should be done by trained personnel.
