Product Description:
The MST210D-0070-FH-N0PU-NNNN is a frameless synchronous torque motor from the MST Synchronous Torque Motors series manufactured by Bosch Rexroth Indramat. As a direct-drive rotary unit, it delivers high continuous torque without gearboxes, supporting precise positioning and smooth speed control in indexing tables, printing cylinders, and similar automation assemblies. Its frameless design allows the motor to be integrated directly into the machine structure, which helps reduce backlash and mechanical compliance. This layout is well suited to applications that require repeatable motion without the added compliance of belts or gear trains.
At its continuous operating point, the motor supplies 150.0 Nm of rated torque while turning at 700 rpm, producing 11.00 kW of mechanical power. That output is achieved with a phase rated current of 32.0 A, and each ampere contributes torque according to a 4.70 Nm/A constant, allowing the drive controller to predict load response accurately. Heat is removed by an aluminum cooling jacket integrated into the housing, and the winding resistance is 1.4 Ω at 20 °C. The 20 pole-pair stator, combined with 6.9 mH of inductance, shapes the electrical time constants for vector control. Power reaches the coils through a connector socket seated in an RLS1200 flange and is supplied through 6.0 mm² conductors sized for the rated current.
The motor can deliver 300.0 Nm of peak torque during acceleration and reach a top speed of 1200 rpm when the controller supplies the 120.0 A maximum current. These transient ratings influence inverter sizing and the allowable moment of inertia of the driven load. The 13.8 kg stator mass provides thermal inertia that assists short overload cycles before coolant flow removes heat. Together with the aluminum cooling jacket, this mass helps maintain winding temperature during cyclic duty operation and supports quick recovery after brief overload bursts. The connector-based power interface and RLS1200 flange help keep installation alignment consistent in modular production lines.
