Product Description:
The MSM215-319-304-M-2KA is a brushless servo motor produced by Kollmorgen in the MSM Brushless Servo Motors series. This three-phase unit is intended for industrial automation tasks that require precise speed and position regulation, such as coordinated axis systems on packaging lines or robotics. By integrating a built-in brake and high-resolution multi-turn feedback, the motor supplies the drive controller with exact rotor position data across multiple revolutions.
It supplies a continuous shaft torque of 36 Nm, so it can hold process loads without overheating under steady operation. During quick moves, the electromagnetic design supports up to 100 Nm of peak torque, providing sufficient acceleration and deceleration capacity. Nominal operation occurs at 3000 rpm when the windings are fed from a 460 V bus, and the corresponding electrical back EMF is 164 V/krpm. The motor has a torque constant of 1.36 Nm/A, which relates commanded current to mechanical output and helps the drive maintain accurate current control. Continuous operation draws a peak current of 28.7 A, while the inverter can momentarily supply a peak current of 93.3 A during overload events. Six magnetic poles establish the required electrical angle, and the high-resolution multi-turn encoder provides feedback for the velocity loop in the drive.
Each phase has an inductance of 10.6 mH and a resistance of 0.40 Ω at 25 °C, which influence the PWM carrier settings and thermal model within the controller. With the brake installed, the rotor has an inertia of 0.0138 kg·m², supporting smooth motion profiles without excessive settling time, and the complete assembly has a mass of 36 kg. The holding brake operates from 24 VDC and secures the shaft when motor power is removed. Torque is transmitted through an M12 × 1.75 mm threaded shaft end, which supports connection to compatible gearbox couplings. The brake helps prevent unintended shaft movement while the axis is stationary or the drive is disabled.
