Product Description:

The MST360D-0012-FT-N2CS-NNNN is a frameless synchronous torque motor produced by Bosch Rexroth Indramat within the MST Synchronous Torque Motors series. Designed for direct-drive tables, extruders, and indexing axes, this stator delivers high continuous torque at low rotational speeds, allowing mechanical transmissions to be removed from the motion chain and improving position accuracy in automated equipment. Its frameless form allows the stator to be integrated directly into the machine structure, which reduces coupling components and helps support compact axis layouts. A continuous phase current of 15.7 A, a winding inductance of 46.2 mH, and a voltage constant of 2.043 V/rpm shape the motor’s dynamic response and back-EMF profile, while a 2.5 mm² power lead cross-section supports the associated conductor temperature rise.

Under continuous operation, the motor delivers a rated torque of 525 Nm while holding a rated speed of 115 rpm. These values indicate the continuous mechanical output available within the stated thermal limits. The electrical conversion is characterized by a rated power output of 6.30 kW and a configuration of 25 pole pairs, so the drive controller must supply matched commutation sequences for smooth rotation. With a torque constant of 33.33 Nm/A, the motor produces substantial torque per ampere, which helps reduce current demand and cabling losses during steady operation.

The motor has a winding resistance of 5.4 Ω, and it permits a maximum phase current of 39.8 A for brief overloads such as acceleration peaks. Leakage capacitance of 13.5 nF should be considered when sizing RFI filters for the drive system. Liquid cooling removes 3.60 kW of dissipation, and the circuit requires a flow rate of 6.0 l/min to keep the stator temperature within its intended operating range. The motor also has a maximum electrical speed of 190 rpm and a stator mass of 28.8 kg, which affect both drive matching and mounting support.
