MST290D-0004-FH-N0PU-NNNN

The Bosch Rexroth Indramat MST290D-0004-FH-N0PU-NNNN from the MST Synchronous Torque Motors series offers precision torque control and robust construction for demanding direct-drive applications. Featuring a rated torque of 350 Nm and a maximum torque of 700 Nm, this motor excels in tasks requiring sustained force and quick response. Its rated speed of 45 RPM and capability to reach a maximum speed of 150 RPM ensure smooth, low-speed motion with ultra-fine position accuracy. Built with a protection category of IP 00, the design focuses on open-frame installations where maximum thermal exchange is prioritized.

Thermal management is reinforced by a liquid cooling system and integrated aluminum cooling jacket, enabling continuous operation under heavy loads without thermal derating. The motor handles a rated power of 1.65 kW and efficiently dissipates a rated power loss of 4.2 kW through stable inlet temperatures of +10 to +40 °C at 3 bar pressure. Electrical performance is assured by a rated current of 10.4 A and a maximum current of 30 A, delivering reliable current-to-torque conversion with minimal ripple. The combination of heavy-duty bearings and balanced rotor dynamics maintains performance even during prolonged cycles.

At just 20 kg stator mass and 9 kg rotor mass, the MST290D-0004-FH-N0PU-NNNN balances inertia for rapid acceleration with the stability needed for precision positioning. A cable connection through the stator end optimizes installation footprint and cabling pathways in compact machine layouts. With a clean, encoder-free rotor design and 30 pole pairs, this synchronous torque motor adapts to customized feedback solutions while delivering seamless torque output for rotary tables, swivel axes, and specialized automation equipment.
