Product Description:

The MSM165-93-204-E2-0KA brushless servo motor is produced by Kollmorgen within the MSM Brushless Servo Motors series. As a rotary actuator, it converts drive current into precise shaft motion for pick-and-place modules, indexing tables, and other automated axes that require closed-loop speed and position control. Its design is optimized for drives with a 460 V bus, and it is supplied without a brake to reduce inertia during dynamic duty cycles.

The motor provides a continuous torque of 10.5 Nm, which it can deliver continuously under rated operating conditions. A rated speed of 2000 rpm pairs this torque with moderate shaft velocity for midrange power applications. When rapid acceleration is needed, the motor supplies up to 34 Nm for short periods, provided that the drive can furnish a peak phase current of 24.0 A. The torque constant of 1.86 Nm/A indicates the relationship between stator current and produced torque, simplifying current-loop tuning. An incremental encoder with 2,000 lines provides position feedback to the drive, while the rated voltage of 460 V supports operation with compatible industrial servo drives. The stall current is limited to a peak of 6.2 A to keep the windings within their permitted thermal range.

Electrical impedance values also influence motor performance. A phase resistance of 5.7 Ω moderates thermal rise during continuous operation, while a winding inductance of 60.0 mH affects the current rise time that the drive must control. Back electromotive force is represented by a voltage constant of 225 V/krpm, so the drive must accommodate the generated voltage as motor speed increases. A rotor inertia of 0.0022 kg·m² balances quick response with load stability during acceleration and deceleration. An M8 × 1.25 shaft thread supports mechanical installation and connection to compatible driven components. The motor has an overall mass of 12.0 kg, allowing it to be mounted directly on a suitably rated machine frame.
