Product Description:
The SM 45-M3000 is a synchronous servo motor built by Kollmorgen. It belongs to the 6SM Synchronous Servo Motors series. The motor converts electrical energy into controlled rotary motion so that positioning tables, pick-and-place axes, or compact spindles can follow precise velocity and torque commands issued by a drive controller in automated equipment.
Under continuous load, the motor delivers 0.5 kW of mechanical power while operating at a nominal speed of 3000 rpm. The corresponding continuous shaft torque is 1.6 Nm, produced when the drive applies a three-phase bus voltage of 400 V to the stator windings. Dynamic events such as rapid acceleration can draw up to 5.6 A of peak current, whereas steady operation draws a rated current of 1.3 A. At standstill, the electromagnetic system can hold 1.7 Nm, which is useful when the load must remain fixed during dwell periods. The rotor inertia of 2.1 kg·cm² helps limit overshoot during speed reversals. A 20-minute thermal time constant indicates how slowly the motor temperature rises, providing headroom for short overloads. The electrical characteristics include a phase inductance of 99.0 mH and a phase resistance of 34.0 Ω. The back EMF is 116 V per 1,000 rpm, which the drive must counteract during vector control.
The motor supports a maximum axial force of 120 N and a maximum radial side load of 370 N, allowing belt tensioners or couplings to act directly on the shaft without causing premature bearing wear. Each ampere of stator current generates torque with a sensitivity of 1.36 Nm/A, allowing the controller to calculate the expected output accurately. The assembly weighs 5.5 kg, making it suitable for installation on compact machine frames while providing enough mass to help damp vibration. Its load capacity supports direct mechanical connections in applications that use belts, pulleys, or rigid couplings.
