Bosch Rexroth's MHD112C motor is a 45-kilogram synchronous motor highly-regarded for its efficiency and versatility. The model R911292678 (MHD112C-058-PG3-RN) features an integrated multiturn absolute encoder, a power connector on the right side of its housing, and a plain shaft for torque transmission. With a voltage and torque constant of 72.7 V/1000min-1 and 0.8 Nm/A at 20 degrees Celsius, the motor's efficiency is remarkable. It offers a housing suitable for both natural and liquid cooling, and is IP65 approved for dust and fluid protection. However, fluid at the output shaft may impact the motor in the IM V3 design. The model has a holding brake with a connection and disconnection time of 53 and 97 milliseconds, aiding in precision tasks. With 4 polar pairs, the motor's winding inductivity and resistivity stand at 1.5 mH and 0.12 ohms. Capable of generating a maximum torque of 148 Nm and speed of 4500 rpm, this motor excels in demanding industrial applications.
