Product Description:
The TTR-5301-137-A-07-C is a frameless direct-drive motor element manufactured by Kollmorgen within the Inland Direct Drive Motors series. It is supplied as a stator and rotor assembly that mounts directly to a machine shaft. This arrangement eliminates belts and gearboxes by delivering torque directly to the load. The direct coupling supports precise positioning and rapid dynamic response in industrial automation platforms.
The rotor is constructed with 6 magnetic poles, which determine the electrical commutation angle and influence torque ripple. Under continuous operation, the motor reaches a rated speed of 6000 rpm, making it suitable for applications that demand high shaft velocity and simple mechanical coupling. Its continuous output capability is 0.8 Nm, allowing the drive to supply moderate torque without thermal derating. A torque constant of 0.62 Nm/A relates commanded phase current to developed torque and supports current-loop tuning. During acceleration or rapid indexing, the unit draws up to 6.5 Arms of peak current, which the selected servo amplifier must be able to supply. The nominal current is 1.5 Arms. At the nominal load, the winding delivers 0.5 kW of mechanical power while balancing efficiency and thermal rise through its copper resistance.
For static holding conditions, the motor can sustain a standstill torque of 1 Nm. Once energized, it overcomes only 0.02 Nm of static friction, allowing fine incremental movements. Electrical behavior at low frequencies is shaped by a winding inductance of 21 mH, which filters current ripple generated by the PWM inverter, while the winding resistance of 12.8 Ω determines resistive losses under load. Back electromotive force is represented by a voltage constant of 38 Vrms/1000 rpm, which helps determine drive bus requirements during regenerative events. The rotor inertia is 0.7 kg·cm², and a two-pole resolver provides angular position feedback for commutation. Thermal equilibrium is reached over a 15-minute time constant, and the fully assembled set weighs 2.3 kg, reducing the added mass on lightweight axes.
