Product Description:

The M.1300.3500 is a brushless servo motor manufactured by Kollmorgen for the NSM Brushless Servo Motors series. As a rotary actuator, it converts drive current into precise position, speed, and torque commands that are fundamental to automated packaging lines, pick-and-place modules, and indexing tables. The model integrates a stator with permanent-magnet excitation and a feedback-ready shaft, allowing it to connect directly to a matched servo amplifier and provide closed-loop motion control without mechanical transmission losses.

Its continuous stall capability is rated at 3.4 Nm, which is the maximum torque the motor can hold indefinitely at zero speed without overheating. For rapid acceleration, the shaft can reach a peak torque of 10.7 Nm, giving machinery a short-term reserve for cutting or press cycles. The electromagnetic design produces 0.38 Nm/A of torque per ampere, so drive sizing can be based on current limits. The windings are configured for a supply of 230 V from the power stage, while a separate brake uses a 24 VDC supply to lock the load when motor power is removed. The copper coils have an inductance of 4.3 mH and a resistance of 0.89 Ω, which influence current ripple and drive bandwidth.

During continuous motion, the motor can deliver 3.8 Nm at shaft speeds up to 4000 rpm, enabling conveyor sections or servo axes to maintain steady throughput without derating. Heat produced by copper losses exits through the housing, which has a thermal resistance of 0.81 °C/W; this value supports surface-temperature calculations for installations inside sealed cabinets. Back electromotive force has a constant of 47 V/krpm, so the generated voltage remains proportional to speed and supports commutation in the associated drive. Cabling and fuse protection should be selected to accommodate the motor current required for continuous and peak torque. Cooling provisions should also account for the installation space, ambient temperature, mounting surface, and expected duty cycle.
