Product Description:
The M-203-S-23 is a rotary servo motor manufactured by Kollmorgen in the M Goldline Servo Motors series. It is intended for closed-loop axes that demand precise speed and position control, such as pick-and-place gantries, packaging machines, and indexing tables. The motor converts commanded current into repeatable torque for industrial automation tasks. Its mechanical envelope follows common IEC mounting conventions, allowing it to fit compatible machinery without requiring frame modifications. Closed-loop feedback enables the connected drive to correct speed and position errors as operating loads change.
The stator housing has a 92 mm body diameter, providing a compact frame that still accommodates the stator material needed for continuous torque generation. At the mounting face, an 80 mm face pilot diameter centers the motor against the machine bracket and limits radial misalignment. Four threaded holes are arranged on a 100 mm mounting bolt circle, matching common servo flanges for straightforward installation. A 14 mm shaft diameter provides a rigid output interface for transmitting torque through compatible couplings. The hardened steel extension has a 30 mm shaft length, giving coupling hubs sufficient engagement without exceeding the available shaft surface. Proper centering at the mounting face also reduces unwanted radial loading on the shaft and connected equipment.
A 5 mm key width is machined along the shaft, creating a positive mechanical interface that prevents slippage between the motor and driven element during rapid acceleration. The enclosure has a standard IP65 rating, which protects internal components from dust and low-pressure water streams encountered in conveyor or filling lines. If greater protection is required, optional gasketing provides a maximum IP67 sealing rating that protects the housing during short periods of immersion under applicable installation conditions. Even with the additional seals and feedback devices, the motor maintains a 275.8 mm overall length, allowing installation in deep cabinets or compact multi-axis assemblies. Adequate axial clearance should be reserved for the motor body, coupling, cables, and any required service access.
