Product Description:

The MTC306B1-S2C1 is a brushless servo motor manufactured by Kollmorgen as part of the MTC Servo Motors series. It is intended for closed-loop speed and position control on packaging stations, pick-and-place axes, and other industrial automation points where repeatable motion is required. A NEMA 34 mounting face allows direct replacement of stepper or older servo frames without mechanical changes, giving machine builders a migration path to higher dynamic performance.

For continuous duty the motor draws a line current of 5.52 ARMS and delivers a stall torque of 3.71 N·m at 25 °C (3.50 N·m when the winding rises to 40 °C). The copper windings exhibit a line inductance of 14.5 mH and a line resistance of 1.94 Ω, parameters that influence current ripple and drive sizing. Back-electromotive force is measured at 38.9 VRMS/krpm, so the drive must supply proportional voltage as speed increases. Nominal operation is rated at 4600 rpm, identical to the specified maximum speed, and at that point the shaft can deliver 1.55 kW of mechanical power. A rotor inertia of 0.0001110 kg·m² keeps acceleration times short while smoothing minor load disturbances. Continuous thermal data are referenced to an IP65 sealed housing that blocks dust and low-pressure water jets.

Short-term overload capability is defined by a peak torque of 11.52 N·m that can be produced with a peak line current of 22.2 ARMS, supporting fast indexing moves. The optional fail-safe brake engages at 24 VDC to hold position during power loss or e-stop events, and the fully gasketed enclosure carries a IP65 rating for use in wash-down or particulate-laden zones. Total mass, including the brake assembly, is 4.8 kg, limiting cantilever loads on smaller gantry plates. With a rated mechanical output of 1.55 kW, the motor balances torque density, thermal headroom, and environmental protection for medium-frame servo applications.
