Product Description:
Kollmorgen SM 45-M-3000 is a Servo motor designed for precise motion control applications. The servo motor features a rated power of 0.5 kW and operates at a rated speed of 3000 min⁻¹. This servo motor is designed to meet the demands of industrial automation systems with reliable torque and performance.
At nominal speed, the SM 45-M-3000 servo motor can produce 1.6 Nm of rated torque, and at rest, it can produce 1.7 Nm of torque. The 6-pole motor design ensures a seamless transmission of torque to the motor. An effective conversion of current to torque is possible due to the torque constant, which is 1.36 Nm/A. There is an inductance of 99.0 mH and a winding resistance of 34.0 Ω between the phases. With a rated current of 1.3 A and a peak current of 5.6 A, the motor is more than capable. Rapid acceleration and deceleration are made possible by the servo motor's 2.1 kgcm² rotor moment of inertia. Minimal mechanical resistance is guaranteed by the static friction torque of 0.131 Nm. Under load, the stable operation is helped by the thermal time constant of 20 minutes. Weighing in at 5.5 kg, the servo motor is built into an IM B5 (Y) frame.
The SM 45-M-3000 servo motor includes a resolver with 2 poles for accurate position feedback. The motor supports a mains supply voltage of 400 V and has insulation class F for thermal protection. The servo motor can withstand a radial load of 370 N at the shaft end. The voltage constant is 116 mV/min, which relates to its back EMF characteristics. These features make the SM servo motor suitable for applications requiring precise torque control and durability in demanding operational cycles.
Frequently Asked Questions about SM 45-M-3000:
