Product Description:
The M.1015.7988 is a brushless servo motor manufactured by Kollmorgen for the HSM Brushless Servo Motors series. It is a rotary actuator that integrates into servo drive systems to convert commanded current into controlled torque and speed, enabling precise positioning of axes in packaging lines, pick-and-place modules, and other automated machinery. Within an industrial control loop, the motor pairs with feedback devices and Kollmorgen amplifiers so mechanical motion tracks electronic commands accurately.
The frame presents a face size of 75 mm; four holes on a 100 mm bolt circle accept M-class fasteners, while each mounting opening is 7 mm in diameter for standard hardware. The steel shaft is 14 mm in diameter and features an M4 × 0.7 mm threaded end with a depth of 10 mm for coupling retention. The overall housing length is 262 mm, providing space for connectors and an integrated brake. The motor delivers a continuous torque of 2.3 Nm and tolerates peaks of up to 6.78 Nm during acceleration. A torque constant of 0.31 Nm/A relates phase current to output torque, allowing the controller to translate current commands into rotary output. The windings are designed for a DC bus of 230 V, and a 24 VDC brake coil can lock the rotor when the axis must hold its position without power.
An electrical back electromotive force constant of 34 V/kRPM indicates the voltage that the motor generates as its speed rises, helping the drive manage commutation and overvoltage limits. The maximum mechanical speed is 6000 rpm, accommodating high-throughput cycles while remaining within bearing and thermal limits. The stator winding has an inductance of 3.4 mH, which smooths current transients and supports stable current-loop control. The winding resistance is 1.3 ohms, contributing to copper losses that must be accounted for by the drive’s thermal model. These electrical values help the motion controller regulate current, acceleration, and braking while keeping operation within the motor’s voltage and temperature limits.
