Product Description:

The MTC304B1-R1C1 is a servo motor produced by Kollmorgen within the MTC Servo Motors series. It is intended for positioning and velocity control in automated machinery, supplying regulated torque over a wide speed range so drive controllers can execute repeatable moves with precise control. The motor’s electromagnetic stack uses 8 poles to support smooth torque at low speed.

This model delivers a rated mechanical output of 0.72 kW, generated at the shaft when the motor runs continuously under nominal conditions. At 25 °C, it can maintain 1.35 N·m of stall torque while drawing a continuous line current of 4.44 ARMS; those values indicate how much load the axis can hold without overheating. The rotor can reach a top speed of 6000 rpm, allowing rapid traverses in indexing tables or pick-and-place heads, and short bursts up to a peak torque of 3.22 N·m provide extra acceleration for overcoming inertial peaks. Line-to-line back EMF is 17.8 VRMS per krpm, so the drive must supply proportional voltage as speed rises. Electrical limits include 250 VRMS maximum applied across the phases and a peak current ceiling of 16.5 ARMS. The thermal network shows 1.001 °C/W resistance at stall and a 22-minute thermal time constant, parameters used by the controller to estimate winding temperature.

Phase windings exhibit an inductance of 11.5 mH and a resistance of 2.24 ohms, figures that influence current ripple and drive tuning. Rotor inertia is only 0.0000465 kg·m², enabling fast reversals with limited servo lag during direction changes. Brake functionality is provided by a 24 VDC holding brake that secures the load during power-off conditions, and with the brake installed, the assembly weighs 3.6 kg. This combination supports compact servo axes that need quick starts and controlled stops.
