Product Description:

The MT1502A1-E2C1 is a brushless servo motor manufactured by Kollmorgen within the MTC Servo Motors series. Designed for closed-loop motion systems, it converts drive current into precise shaft torque so packaging lines, small conveyors, and semiconductor tools can achieve repeatable positioning cycles. The motor interfaces with Kollmorgen amplifiers through sinusoidal commutation and provides feedback suitable for high-speed automation applications.

The motor generates a back electromotive force of 12.2 V RMS/krpm, which the drive uses to calculate voltage requirements across the operating range. Continuous operation at the rated speed of 6000 rpm is supported by a current of 2.21 A RMS. When this current flows through the 6.85 Ω phase resistance, copper losses remain within the 0.23 kW thermal design envelope. At a winding temperature of 40 °C, the motor can maintain a continuous stall torque of 0.438 N·m with magnetic excitation from its eight-pole rotor. A stator inductance of 13.2 mH shapes the current rise time, allowing the controller to apply torque with minimal overshoot. The torque sensitivity of 0.202 N·m/A RMS links the commanded current directly to the torque delivered at the shaft.

For transient moves, the drive may supply a peak current of 7.2 A RMS, enabling the motor to develop a maximum torque of 1.25 N·m for rapid acceleration. The motor can accept a line potential of up to 250 V RMS, and the aluminum housing provides a thermal path with a resistance of 1.33 °C/W. Stored heat dissipates gradually, as indicated by a thermal time constant of 12 minutes, so intermittent overloads require adequate recovery periods. Motion response is aided by a low rotor inertia of 0.0000127 kg·m². With static friction limited to 0.0072 N·m, this low inertia allows the axis to reverse direction quickly without requiring excessive controller gain.
