Product Description:

The MTC304A1-R2C1 is a permanent-magnet servo motor manufactured by Kollmorgen in the MTC Servo Motors series. It converts drive current into controlled mechanical rotation for indexing tables, pick-and-place heads, and similar automation nodes that demand repeatable positioning. A spring-applied brake energized at 24 VDC secures the shaft when power is removed, adding holding capability for vertically mounted loads and for axes that must remain fixed between moves.

At its rated operating point, the motor turns at 3000 rpm and develops mechanical power of 0.70 kW. To reach this operating point, it draws a continuous line current of 2.59 ARMS while its three-phase stator sees a line-to-line voltage of 250 VRMS. The back electromotive force is 59.6 VRMS / krpm, giving the drive controller a predictable voltage constant for field-oriented control. Continuous stall torque is 2.68 N·m at 25 °C and falls slightly to 2.52 N·m at 40 °C as copper temperature rises. A torque sensitivity of 0.985 N·m per amp links commanded current to delivered torque, and a DC resistance of 7.93 Ω contributes to steady-state copper losses in the windings.

For short-duty bursts, the motor can reach a peak torque of 7.40 N·m when the drive supplies a peak line current of 10.0 ARMS. Acceleration behavior is influenced by a rotor inertia of 0.0000808 kg·m², which helps the axis respond quickly without demanding excessive current from the drive. The phase inductance is 58 mH, so current rise remains controllable even with high pulse-width-modulated voltages. Mechanical dimensions are compact, with an overall length of 183.1 mm and a shipping mass of 4.3 kg including the brake. Its compact size and moderate mass suit light gantries and other machine axes where installation space is limited.
