Product Description:

The MST360E-0018-FT-N0CN-NNNN is a direct-drive rotary motor produced by Bosch Rexroth Indramat within the MST Synchronous Torque Motors series. Designed as a stator component for torque-dense applications, the unit supplies high continuous torque at very low speeds, allowing gearless positioning tables, winding drums, and test stands to couple the load directly to the shaft. In plant automation, the motor’s flat speed-torque curve eliminates mechanical backlash and reduces maintenance compared with gearbox-based drives.

Its thermal management relies on liquid cooling, with coolant routed through internal channels in the stator laminations. The required flow rate of 6.0 l/min keeps winding temperatures within limits during prolonged load periods. For transient peaks, the windings can accept 141.0 A of phase current, generating up to 1900 Nm of electromagnetic torque before magnetic saturation occurs. At 20 °C, the torque constant is 20.80 Nm/A, so control electronics can predict output torque from measured current with linear correlation. The stator receives coolant through side connectors, while the larger-diameter electrical connector places power terminals on the outer rim to simplify busbar access.

Under continuous duty, the motor draws 42.0 A to deliver 16.50 kW at the rated point of 180 rpm, yielding a stable shaft output of 875 Nm without exceeding permissible copper temperatures. When halted, the drive can hold 1050 Nm of standstill torque at 50.4 A, supporting static clamping loads until motion resumes. A thermally conductive resin fills the winding cavities to provide mechanical strength and absorb vibration. The 40.3 kg stator pairs with 10 mm² conductors to limit voltage drop along the feed. With its encapsulated windings and liquid circuit, the assembly maintains steady performance in continuous processing lines.
