The MHD112C-058-PG3-RN, a product of Bosch Rexroth Indramat, is a synchronous motor with an embedded multiturn absolute encoder and a right-side power connector. This model displays voltage and torque constants of 72.7 V/1000min-1 and 0.8 Nm/A respectively at a 20°C temperature. It is designed with a plain shaft and a 45 kg metallic housing that's suitable for both natural and liquid cooling. This motor's IP65 certification ensures protection against dust and fluids, making it ideal for motion control systems. It incorporates four polar pairs and has winding inductivity and resistivity of 1.5 mH and 0.12 ohms respectively. The device is equipped with a 3.8 kg holding brake with a torque of 70 Nm and connects and disconnects within 53 and 97 milliseconds respectively. With surface cooling, it performs at a maximum speed of 3500 rpm and maximum torque of 43.5 Nm consuming a current of 43 A. It delivers a peak torque of 148 Nm and peak speed of 4500 rpm. With 100 K natural cooling, it operates at a rated power of 8 kW, producing a torque of 16.9 Nm and frequency of 233 Hz, with a thermal time constant of 90 minutes.
