Product Description:
The MST160E-0050-FT-N0CN-NNNN stator belongs to the MST Synchronous Torque Motors series produced by Bosch Rexroth Indramat. This frameless torque motor component is intended for direct-drive rotary tables, indexing heads, and automation axes that demand high torque at low speed without backlash from gearboxes. Because the stator mounts directly into the machine structure and works with a permanent-magnet rotor, the drive can deliver smooth servo motion while leaving a large through-bore available for cables, air lines, or product flow.
Under continuous duty, the motor develops a rated torque of 105 Nm while turning at a rated speed of 500 rpm, producing mechanical output power of 5.50 kW. To reach this operating point, the stator draws a rated current of 19.5 A, and its torque constant of 5.38 Nm/A indicates how much torque is produced for a given current. Fifteen pole pairs support precise electrical commutation at low shaft speed, and the 12.8 mH winding inductance helps moderate current rise during dynamic load changes. Copper losses appear as 3.2 Ω of resistance and contribute to a steady power loss of 3.00 kW, which must be removed by the integrated liquid-cooling jacket to keep winding temperature under control.
During overload, the stator can provide short bursts of higher output for acceleration and indexing moves. Peak acceleration can demand a maximum torque of 270 Nm, while the drive may momentarily supply a maximum winding current of 60.0 A. Heat rise is limited by a thermal time constant of 7.0 min, so temperature can increase quickly if coolant flow is inadequate. The stator channels need a coolant flow of 4.3 L/min with an inlet pressure no higher than 3.0 bar to remove the stated losses, and the 13.9 kg mass allows the unit to cool quickly after the load drops.
