Product Description:
The M.1015.7986 servo motor is manufactured by Kollmorgen and belongs to the HSM Brushless Servo Motors series. Designed for closed-loop positioning and velocity control, the unit can couple directly to machine shafts in packaging lines, pick-and-place arms, and indexing tables. An integrated electromagnetic brake allows the axis to hold its load when power is removed. An incremental encoder replaces resolver feedback in this configuration, providing compatibility with servo drives that support incremental position signals.
During continuous operation, the motor delivers 0.80 Nm of torque at the shaft, making it suitable for small actuators and light rotary tooling. For short bursts, it withstands a peak torque of 2.94 Nm, providing additional acceleration for indexing loads. The electromagnetic circuit produces torque in proportion to current, and its torque constant of 0.31 Nm/A supports accurate current-loop control. The back EMF constant is 34 V/kRPM, which must be considered when selecting the drive and DC-bus voltage. The brake coil requires 24 VDC for operation. A rotor inertia of 0.000038 kg·m² supports rapid acceleration and deceleration, while static friction is limited to 0.014 Nm for consistent motion after the brake releases.
The phase windings have an inductance of 12 mH and a resistance of 6.6 Ω, affecting voltage demand and current ripple under pulse-width modulation. Heat produced by copper losses is conducted through the aluminum frame, and the thermal resistance of 1.2 °C/W supports temperature-rise calculations for continuous operation. Position feedback is provided by an incremental encoder that delivers 2000 quadrature pulses per revolution and supports 8,000 counts per revolution after quadrature decoding. The housing measures 211 mm in length with the brake installed and uses a 100 mm bolt circle for mounting. The shaft includes M4 × 0.7 threads with a depth of 10 mm, while the mounting holes have a diameter of 7 mm. These interfaces allow the motor to be secured to a compatible machine frame and connected to the driven mechanism without requiring an intermediate belt assembly.
