Product Description:

The M.1015.6956 is a brushless servo motor manufactured by Kollmorgen for the NSM Brushless Servo Motors series. This unit is intended for industrial automation tasks that demand precise and repeatable rotary motion, such as pick-and-place gantries, indexing tables, and electronic assembly heads. When coupled to a compatible servo amplifier, the motor converts controlled current into proportional shaft torque, allowing position, speed, and acceleration to be regulated through closed-loop feedback.

The continuous stall capability of 13.8 lb-in is the torque the motor can hold indefinitely without overheating, while the maximum continuous shaft speed of 5500 rpm is the top operating velocity at rated voltage. A sine-wave torque constant of 3.0 lb-in/A and a square-wave constant of 3.3 lb-in/A translate phase current into usable torque under different commutation schemes. The generated back EMF is proportional to speed at 40 V/krpm, so the control drive must supply a bus voltage that exceeds this value and provides sufficient overhead for modulation. Thermal behavior is characterized by a rating of 1.2 °C/W, indicating the rise in winding temperature for every watt of loss. Electrical dynamics are set by an inductance of 8.6 mH, which filters current ripple, and a resistance of 2.7 Ω that contributes to resistive heating.

For transient moves, the motor can deliver up to 36.0 lb-in of peak torque. Rotor position is reported by an optical encoder that provides 2000 lines per revolution. Its differential outputs are driven by a 26LS31 device, producing a logic-high voltage of at least 2.5 VDC and a logic-low voltage no higher than 0.5 VDC when supplied with 5 VDC at up to 300 mA. A shaft-mounted holding brake rated for 24 VDC engages when control power is removed, securing vertical or safety-critical axes during idle states.
