Product Description:

Bosch Rexroth Indramat produces the MST360E-0018-FT-N0SN-NNNN as part of the MST Synchronous Torque Motors series. This frameless stator assembly is intended for direct integration into machine housings where slow, high-torque rotation is required. By providing electromagnetic torque directly to the load without mechanical reduction, the unit supports precise speed control and eliminates backlash in industrial automation tasks such as rotary positioning tables, plastic extruders, and large indexing drives. Its water-cooled construction supports sustained thermal performance under continuous duty and helps maintain stable operation in production environments.

The motor is equipped with a 210 mm water-cooled jacket that routes coolant around the stator laminations. This liquid circuit maintains winding temperature while the unit produces a continuous output torque of 875 Nm at a nominal shaft speed of 180 rpm. Under these operating conditions, it delivers 16.5 kW to the load and draws a phase current of 42 A. When peak acceleration is required, the drive electronics may supply up to 141 A for short intervals. A stator mass of 40.3 kg also helps absorb heat during operation. The electromagnetic circuit has a winding inductance of 21 mH and a resistance of 1.3 Ω per phase, which affect current rise time and copper losses.

The motor's overload capability allows momentary output up to 1900 Nm without mechanical gearing. Drive current is converted into output torque at a proportional rate of 20.80 Nm/A, which helps relate current demand to torque production, while the back EMF rises at 1.890 V per min⁻¹ of speed for commutation. Mechanical integration is aided by an outer jacket diameter of 385 mm, and the open housing with protection code IP00 requires installation inside a clean, closed machine frame with an independent coolant supply.
