Product Description:

The MTC1506B1-E1C1 is a brushless servo motor manufactured by Kollmorgen for the MTC Servo Motors series. It is intended for industrial automation axes that demand precise velocity regulation, repeatable positioning, and the ability to integrate an electromechanical brake for static holding. By converting controlled stator currents into rotary motion, the unit delivers closed-loop performance to packaging equipment, pick-and-place modules, and small robotic joints. Its brushless construction supports smooth torque delivery and avoids the wear associated with mechanical commutation.

At a winding temperature of 25 °C, the motor supplies 1.474 N·m of continuous stall torque, while at 40 °C the value decreases to 1.384 N·m because of higher thermal resistance. The continuous line current is 5.86 ARMS, based on a 1.34 Ω phase-to-phase resistance and a line-to-line inductance of 3.7 mH. This electrical combination helps the drive regulate current during starts, stops, and reversals. The motor permits a maximum applied voltage of 250 VRMS between phases, and the brake uses a 24 VDC coil for holding at standstill. For dynamic cycles, the motor can absorb a peak line current of 22.7 ARMS, generating short-term torque without magnet saturation. Both the rated and maximum mechanical speed reach 6000 rpm, which suits high-speed servo axes driven by wide-bandwidth controllers.

The energy conversion characteristics include a rated output of 0.65 kW and a peak torque of 4.67 N·m for acceleration events. Back electromotive force is rated at 14.5 VRMS/krpm, which helps match the motor to the drive’s available voltage range. A rotor inertia of 0.0000317 kg·m² supports quick load changes with limited overshoot, and the thermal time constant of 24 minutes shows how quickly the winding temperature approaches equilibrium. With the spring-applied brake installed, the complete assembly weighs 2.3 kg, which supports compact mounting on gantries or tabletop machines. The low moving mass is also helpful where short cycle times and fast direction changes are required.
