Product Description:

The MTC302A1-R2C1 servo motor is produced by Kollmorgen within the MTC Servo Motors series. It is a brushless rotary unit intended to deliver closed-loop speed and position control for automated machinery, indexing tables, and pick-and-place axes. By converting electrical power from a matched drive into mechanical torque, the motor provides direct rotary output for applications that require quick response and repeatable motion. This arrangement allows the motor to drive loads directly in many cases, reducing the need for extra transmission components. Its compact form also suits machines where available installation space is limited.

At its rated operating point, the motor spins at 4500 rpm, supplying continuous mechanical power of 0.59 kW while drawing 2.44 ARMS from the drive. Continuous stall torque of 1.37 N-m is available at 25 °C, and short dynamic events can be met with peak torque up to 3.23 N-m. The eight-pole rotor develops back electromotive force of 32.6 VRMS/krpm, which the controller uses when calculating voltage command levels. A line inductance of 35 mH and a winding resistance of 7.77 ohms shape the current-loop response of the motor and drive combination. The windings may be driven from buses up to 250 VRMS without exceeding the insulation rating, and transient demand can pull as much as 9.0 ARMS from the inverter.

Thermal behavior is suited to cyclic duty rather than abrupt heat buildup during changing loads. The copper and steel mass gives the motor a thermal time constant of 22 min, so average losses rise slowly during operation. Rotor inertia of 0.0000465 kg-m² supports fast acceleration with modest drive effort, and the shaft includes a 20 mm key to secure couplings. When a holding function is needed, the integrated brake engages at 24 VDC. With the brake fitted, total mass is 3.6 kg, which helps keep payload impact low on moving axes.
