Product Description:
The M.1015.6977 is a brushless servo motor manufactured by Kollmorgen within the YSM Brushless Servo Motors series. It serves as a compact rotary actuator for industrial automation axes that require closed-loop positioning and velocity control. Integrated feedback from its built-in optical encoder allows a drive to synchronize shaft motion with commanded profiles, making the unit suitable for pick-and-place heads, indexing tables, and lightweight gantry systems where precise travel and repeatable torque delivery are critical.
During continuous operation, the motor supplies 1.4 Nm of torque, while momentary demands can be met with a peak capability of 3.8 Nm. Speed modulation is available up to 4500 rpm, enabling rapid moves between work points without sacrificing positional accuracy. Current passes through distributed windings that have an inductance of 12.4 mH and a resistance of 2.9 Ω, establishing the electrical time constant that the drive must manage. An embedded encoder delivers 2000 pulses per revolution, allowing the controller to resolve movement to 0.18 mechanical degrees per pulse. Dynamic response is aided by a rotor with an inertia of only 0.000026 kg·m², and eight magnetic poles generate the alternating fields required for smooth sinusoidal commutation. Torque production scales at 0.37 Nm/A on a sine basis and 0.40 Nm/A on a square-wave basis, values that help with current-loop sizing. A thermal resistance of 1.3 °C/W indicates the temperature rise for every watt dissipated, while a voltage constant of 45 V/krpm links back electromotive force to shaft speed.
The front bearing can support up to 10 kg of axial thrust, and the radial bearing set withstands side forces of up to 25 kg. These capacities allow the motor to carry belts, pinions, or light pulleys without auxiliary supports. A voltage class of 230 V aligns the winding insulation with common servo drives, while eight stator slots balance copper fill against thermal capacity. The motor has an overall weight of 1.9 kg, permitting installation on moving axes with minimal added mass.
