Product Description:

The M.1015.7987 is a brushless servo motor produced by Kollmorgen as part of the HSM Brushless Servo Motors series. The design couples a permanent-magnet rotor with stator windings optimized for vector drives, allowing rapid torque regulation and speed control. In automated pick-and-place stations, small conveyors, and indexing tables, the unit supplies precise rotary motion that PLCs can synchronize with sensors for repeatable positioning within industrial automation cells.

The motor delivers a continuous shaft output of 0.8 Nm, while short-term demands can be met with up to 2.94 Nm of peak torque, giving the motor a 3.6:1 overload margin for acceleration bursts. A torque constant of 0.31 Nm/A links commanded phase current to generated torque, and the back-EMF constant of 34 V/krpm indicates the voltage the drive must overcome as speed rises. With a rated supply of 230 V, these electromagnetic parameters align with common single-phase bus converters used in compact servo amplifiers. The rotor can support 90 lb of radial load at 1,000 rpm, so moderate belt tensions or pinion forces do not shorten bearing life. Brake control requires 90 VDC, and when the brake is fitted, the overall length becomes 211 mm, allowing adequate space to be reserved around the motor.

The electrical impedance seen by the drive is determined by a phase inductance of 12 mH and a phase resistance of 6.6 ohms at 25 °C, limiting current ripple and affecting thermal rise during continuous operation. Mounting uses a 100 mm bolt circle, four holes measuring 7 mm in diameter, and a thread depth of 10 mm, allowing the frame to attach directly to standard metric flanges. The stainless steel shaft terminates in an M4 × 0.7 mm thread for coupler retention. The motor is rated to withstand shock levels up to 10.0 g peak and vibration amplitudes of 2.5 g peak. These ratings support operation in mobile or high-impact machinery while helping the feedback system maintain accurate position data.
