Product Description:

The M.1015.8003 is a brushless AC servo motor manufactured by Kollmorgen for the HSM Brushless Servo Motors series. Intended for industrial automation axes that require precise position and velocity control, it converts drive current into accurately controlled mechanical torque so machinery such as packaging stations or pick-and-place robots can synchronize motion across multiple axes. The motor delivers a continuous shaft output of 9.9 Nm, which it can sustain indefinitely without overheating.

For rapid acceleration, the motor can reach a peak torque of 30.5 Nm, providing additional capacity for short load surges. A torque constant of 0.81 Nm/A links commanded current to developed torque, allowing the drive to predict output force with linear scaling. The stator is wound for a nominal bus voltage of 230 V, so a compatible three-phase inverter can energize it directly. Back electromotive force is rated at 90 V/kRPM; this proportionality helps establish controller speed limits because the generated voltage rises with rotational velocity.

The mechanical interface follows a 145 mm bolt circle with 10 mm through holes, simplifying attachment to gearboxes or machine frames. The overall length, including the fail-safe brake, measures 368 mm, and the assembly weighs 12.2 kg, which affects axis inertia and available installation depth. Shaft position is reported by an encoder that produces 2,000 quadrature pulses per revolution for precise feedback. The windings have an inductance of 5.4 mH and a resistance of 0.90 Ω, which the drive uses to set current-loop bandwidth. The rotor inertia is 0.00068 kg·m², affecting acceleration and deceleration response under changing loads. The bearing system supports a 215 lb radial load at 500 rpm without premature wear. The integrated brake operates from 24 VDC and locks the shaft during a power loss.
