Product Description:

The 00-01203-M04 is a frameless rotary motor segment produced by Kollmorgen for the DDR Direct Drive Motors series. Intended for direct coupling to machine load shafts, the motor eliminates gearboxes and belts, allowing motion systems to achieve higher positional accuracy and faster dynamic response. Its electromagnetic core is supplied as a kit containing rotor and stator parts that can be embedded into indexing tables, semiconductor tools, or packaging actuators where compact size and low maintenance are priorities.

With a continuous stall torque of 137 N-cm, the motor can support static or low-speed loads without overheating. Its rated operating speed is 3000 rpm, balancing torque production and thermal dissipation. The winding generates up to 396 W of mechanical power at that operating point, while a back-EMF constant of 18.50 V/krpm relates shaft velocity to induced voltage for drive sizing. For transient movements, the design permits rotation up to a maximum recommended speed of 6000 rpm. The motor has an overall diameter of 139.7 mm and a length of 70.6 mm, allowing installation in compact machine assemblies. Its terminal resistance is 0.750 Ω, which affects current draw during low-speed operation or holding conditions, and the assembly weighs 5.0 kg to provide moderate thermal mass without excessive inertia.

During rapid indexing, the motor reaches a peak torque of 1465 N-cm when the drive supplies a peak current of 84 A. Its torque constant of 17.68 N-cm/A converts commanded current into predictable shaft torque for real-time control loops. The rated terminal voltage of 62.7 V is suitable for common low-voltage servo buses. A continuous current rating of 7.9 A supports sustained operation and produces 126 N-cm at 25 °C or 112 N-cm at 40 °C. These temperature-dependent torque values can be used to select suitable heat sinks and maintain the required thermal conditions within the machine.
