Product Description:

The CH054A-13-3105 is a cartridge-style direct-drive rotary motor manufactured by Kollmorgen and supplied in the Cartridge DDR Motors series. As a frameless assembly that mounts through its 45 mm center bore, the motor couples directly to the load. This arrangement removes belts or gearboxes and provides precise torque for index tables, pick-and-place heads, and other automation axes. It also reduces mechanical compliance and backlash in precision rotary systems.

At standstill, the motor can deliver a continuous torque of 24.8 N-m while drawing 9.79 Arms of current. The electromagnetic conversion is characterized by a torque constant of 2.57 N-m/Arms and a back-EMF constant of 155.5 Vrms/kRPM, allowing predictable current-to-speed behavior. Winding parameters include 1.35 ohms of DC resistance at 25 °C and 9 mH of inductance, which affect drive voltage requirements and current-loop response. The rotor carries 10 poles and has an inertia of 0.00528 kg·m², supporting fast indexing without excessive regenerative energy. The stator diameter is 138 mm and the installed length is 194.7 mm, so the motor fits compact machine envelopes while retaining the stiffness expected from a frameless direct-drive design.

During transient events, the motor withstands 63.5 N-m of peak torque when supplied with 26.4 Arms of current. The overload margin lets motion controllers apply aggressive jerk profiles without saturating the magnetic circuit. Under 400 VAC excitation, it achieves a rated output of 4.47 kW at 2100 RPM, giving machines a balance of speed and torque for rapid cycles. The 15.4 kg frame disperses heat generated by copper losses and supports secure mounting through the cartridge flange. After short overloads, the thermal path allows the windings to return to continuous operation.
