Product Description:
Bosch Rexroth Indramat supplies the MST360E-0018-FH-N0KR-M260 as part of the MST Synchronous Torque Motors series. This low-speed, high-torque motor is intended for direct-drive tables, winders, and similar automation axes where gearboxes are undesirable. By generating large static torque at very low shaft speed, it allows the load to be coupled directly to the rotor and held with high precision. This direct-drive arrangement can also reduce backlash and wear from intermediate transmission components.
The motor’s output ceiling is set by a maximum torque of 1900 Nm, which can be reached when the inverter delivers up to 141 A. A rotor moment of 0.44 kgm² moderates acceleration and cushions load shocks, while the electromagnetic design uses 25 pole pairs to support smooth rotation at low frequencies. Power conductors with a cross-section of 10.0 mm² are required to carry the rated and peak currents without excessive heating. Transient voltage spikes are limited by an internal discharge capacity of 20.0 nF, and the 21 mH winding inductance helps filter high-frequency drive switching to reduce torque ripple. These values describe the motor’s dynamic behavior and the conductor size required for reliable integration.
Continuous operation is based on a rated power of 16.5 kW, obtained when the shaft turns at 180 rpm and produces rated torque under steady current demand. A torque constant of 20.80 Nm/A links commanded current to produced torque, so a tightly regulated drive can translate small current changes into predictable load motion. This behavior supports smooth indexing and controlled holding in rotary applications. The voltage constant of 1.890 V min⁻¹ indicates the back EMF generated per speed unit and supports field-oriented control in the drive. Heat losses are influenced primarily by a winding resistance of 1.3 ohms, which helps determine the cooling required to keep the windings within their insulation limit.
