Product Description:

The MTC306B1-R2C1 is a brushless servo motor manufactured by Kollmorgen as part of the MTC Servo Motors series. It is intended for closed-loop industrial axes that demand repeatable velocity and position, converting electrical energy into controlled rotary motion. The motor includes an integrated electromagnetic brake so machinery can remain stationary whenever the drive is disabled. This arrangement is useful on indexing and vertical axes where the load must stay in place between motion cycles.

During continuous operation, the windings draw 5.35 ARMS and can hold the shaft with a stall torque of 3.32 N-m at 40 °C. Copper losses are influenced by a direct-current resistance of 1.94 Ω measured at 25 °C, while a 17 mH line inductance helps limit current ripple from the inverter. Acceptable bus potential reaches 250 VRMS; above this value, insulation stress may exceed design limits. When the motor reaches its rated speed of 4600 rpm, it outputs 1.47 kW of mechanical power, and the generated back electromotive force scales at 38.1 VRMS/krpm. These values describe the operating range that the matching servo drive must support during normal running conditions.

For transient moves, the drive may deliver 22.2 ARMS to the stator, letting the rotor generate a peak torque of 11.29 N-m for rapid acceleration. A brake coil rated at 24 VDC clamps the shaft once motion stops, assisted by 0.052 N-m of static friction. Dynamic response is influenced by a rotor inertia of 0.000111 kg-m², which supports quick reversals without excessive overshoot. Thermal behavior relies on a 0.795 °C/W winding-to-case path and a 31-minute thermal time constant, so intermittent overloads can be absorbed before equilibrium is reached. With the brake installed, the unit weighs 4.8 kg, which is relevant on gantry or robot axes where moving mass affects cycle time.
