MST290D-0004-FS-N0CN-SG01

MST290D-0004-FS-N0CN-SG01 from Bosch Rexroth Indramat is part of the MST Synchronous Torque Motors series. This synchronous torque motor features a winding code of 0004 and benefits from an integrated stator-cooling jacket designed for liquid cooling. It delivers high continuous torque at low speeds and is optimized for precision positioning applications. Fully compliant with DIN EN 60034-1 testing standards, it provides dependable performance in industrial environments.

The motor’s detailed specifications include a rated velocity of 45 rpm and a rated power of 1.65 kW, rising to a max velocity of 150 rpm under reduced torque. Its discharge capacity of 12.6 nF and winding inductance support smooth current transition, while the thermal time constant of 3.3 minutes ensures stable thermal behavior during extended operation. The frame with a Length designation of D and a motor size of 290 yields a stator mass of 20 kg. Thermal loads up to 4.2 kW are efficiently removed via the liquid cooling mode system, supplying coolant at inlet temperatures from 10 °C to 40 °C through a 0.31 l duct at pressures up to 3 bar.

Engineered for seamless integration, the MST290D-0004-FS-N0CN-SG01 accepts a cable conducted power connection at the stator end, simplifying installation in compact machine frames. Its robust liquid-coolant jacket and proven torque-to-current ratio of 33.7 Nm/A provide consistent output under variable loads, enhancing reliability in continuous-duty applications. Ideal for low-speed servo positioning, spindle drives, and torque-testing rigs, this motor delivers precise, maintenance-friendly operation.
