Product Description:
The XSM115-42-504-S-2AA is a brushless permanent-magnet motor manufactured by Kollmorgen for the XSM Centurion Servo Motors series. It serves as a compact drive element for numerically controlled axes, conveyors, and indexing tables that require tight speed regulation and responsive torque in industrial automation environments. A high-energy rotor supports efficient torque production across the operating range. Integrated SinCos feedback provides the position information needed for precise electrical commutation when the motor is paired with a compatible Kollmorgen drive.
The motor reaches a maximum mechanical speed of 5000 rpm, which is the upper velocity limit that the controller must supervise. During brief overloads, it delivers up to 13.5 Nm of peak torque, while a torque constant of 0.83 Nm/A allows the drive to convert commanded current into shaft torque. The back-EMF slope is 100 V/krpm, indicating how generated voltage increases with motor speed. A phase inductance of 21 mH moderates the current rise time and supports smooth drive switching. The windings are designed for 460 V operation, and the motor provides 42 in-lb of continuous torque. An optional 24 V holding brake extends the housing by 1.91 inches and can secure vertical or inertial loads when power is removed.
The motor has a square mounting face measuring 115 mm, supporting installation on compatible machine frames and mounting plates. Its bearings withstand up to 45 kg of radial force at maximum speed, allowing the motor to accommodate appropriate belt tension or overhung gear loads. Axial force may reach 18 kg under the same operating condition. A rotor inertia of 0.00026 kg·m² supports rapid acceleration and responsive changes in speed. The stator windings have a resistance of 3.8 Ω, which influences copper losses and current-loop behavior. SinCos feedback reports position over one mechanical revolution, while the smooth shaft without a keyway accepts clamp-style couplings. The shaft end also includes an M6 × 1.0 mm thread with a depth of 16 mm for securely attaching compatible tooling or retaining hardware.
