Product Description:

The M-605-B-21-B3E102 is an AC servo motor produced by Kollmorgen within the M Goldline Servo Motors series. It converts controlled current from a matched servo drive into precise rotational motion for industrial automation equipment such as packaging lines, robotics, and machine tools. By supplying closed-loop torque and speed control, the unit serves as the mechanical actuator that positions loads accurately through repeated duty cycles.

At a winding temperature of 25 °C, the motor sustains a continuous torque of 31.8 N-m while drawing a continuous phase current of 27.7 A RMS. Its insulation allows connection to drives that supply up to 250 VRMS line-to-line without dielectric failure. The rated shaft speed is 3150 RPM, which is the steady operating point for the motor under load. For rapid acceleration or transient disturbances, the electromagnetic circuit can reach a peak torque of 87.7 N-m, which the drive must support for short intervals. The bearing system and mechanical layout are intended for stable operation throughout the motor’s normal speed range.

When the winding temperature rises to 40 °C, continuous torque derates to 30.1 N-m, indicating the thermal margin that must be observed during prolonged high-load operation. Brief overloads may demand a peak phase current of 84.8 A RMS, so power cabling and fusing must be sized accordingly. The rotor employs 6 poles, which sets the electrical commutation frequency that the amplifier synthesizes for smooth rotation. At the rated operating point, the motor delivers 7.7 kW of mechanical power, which is useful when selecting the driven load and matching the motor to the application. These values help confirm that the motor is suited to applications that require controlled torque, steady speed, and short-duration overload capability.
