Product Description:
The NSM5630 is a brushless servo motor manufactured by Kollmorgen within the NSM Brushless Servo Motors series. In industrial automation, the unit operates as a high-precision rotary actuator, transforming electrical commands from a drive into mechanical motion for pick-and-place modules, small conveyors, and indexing tables. Its permanent-magnet design delivers consistent torque across the speed range while eliminating brush wear, which improves uptime in continuous-duty production cells. The motor supports controlled positioning, speed regulation, and repetitive motion in applications that require responsive operation.
Under steady load, the motor supplies 3.8 Nm of continuous torque, providing a predictable baseline for holding force or constant-speed operation. During acceleration or brief overloads, it can reach a peak output of 10.7 Nm, allowing fast cycle times without requiring a larger frame. The current-to-torque conversion is represented by a torque constant of 0.38 Nm/A, allowing the drive electronics to determine the current needed for a commanded torque. The back-electromotive-force constant of 47 V/kRPM indicates the voltage generated by the stator as motor speed increases, which is important when matching the motor to DC-bus limits and regenerative braking thresholds. Dynamic behavior is influenced by the rotor’s moment of inertia of 0.00090 kg·m². This low inertia supports rapid starts and stops while reducing the energy needed to change shaft speed.
The electromagnetic circuit has a phase-to-phase inductance of 4.3 mH, which filters current ripple and helps stabilize torque during pulse-width modulation switching. The copper windings have a phase-to-phase resistance of 0.89 Ω at 25 °C, establishing a baseline for thermal dissipation and influencing the continuous current rating. The shaft and bearing set tolerates a radial load of 85 kg at 500 rpm, making the motor suitable for belt drives or moderately overhung pulleys. With a total mass of 9.1 kg, the assembly can be mounted on moving carriages without adding excessive mass to the axis. The bearing arrangement supports external loads while allowing the rotor to maintain stable alignment during repeated acceleration and deceleration.
