Product Description:
Kollmorgen’s MSM215-221-304-E2-2KA is a Brushless servo motor designed for precise motion control in industrial automation. The servo motor uses electronic commutation, which eliminates the need for brushes, resulting in more efficient operation and lower maintenance requirements.
The MSM215-221-304-E2-2KA servo motor can operate at a maximum speed of 3000 rpm and delivers a constant torque of 221 in-lb (25 Nm) as well as a peak torque of 620 in-lb (70 Nm). Both the voltage and torque constants are 161 V/KRPM and 1.34 Nm/Amp, respectively. At 25°C, the winding inductance is 15.8 mH and the winding resistance is 0.76 ohms phase-to-phase. The peak current that the motor can handle is 65.1 amps, and its stall current is 13.6 amps. A shaft composed of ST-60 material constructs the rotor, which has six poles. The moment of inertia for the rotor is 0.0655 lb-in² (0.0044 kg-m²) when no braking is applied and 0.0920 lb-in² (0.0104 kg-m²) when friction is present. The servo motor is built to last and consistently performs due to its strong shaft material and defined inertia.
The MSM215-221-304-E2-2KA brushless servo motor is rated for an ambient temperature range from 0 to 40°C and a storage range from -30 to 70°C. The motor is designed to operate in relative humidity from 5% to 95% non-condensing. The electronic commutation mechanism maintains a constant speed and torque under variable loads, while the permanent magnet rotor delivers high torque density and efficient power conversion. The servo motor provides a high torque, controlled speed, and dependable operation, all supported by a feedback system that allows for precise positioning and motion control. The design includes a voltage constant, which allows for compatibility with a wide range of servo drives.
