Product Description:
The CTM22NLF06NEE00 is a two-stack hybrid stepper motor produced by Kollmorgen within the CT Stepper Motors series. As a positioning element, it translates pulse trains from an indexer or microstepping drive into discrete shaft increments. This operation gives machine tools, printers, and pick-and-place axes open-loop motion control without requiring rotary encoders.
This model delivers a holding torque of 3.32 Nm, so the shaft can resist back-driving forces whenever the windings remain energized. To achieve that torque, the drive must supply 0.60 A per phase, which helps minimize heat rise in compact enclosures. The copper windings have a phase resistance of 32.2 ohms and a phase inductance of 108 mH. These electrical values establish a time constant that affects current buildup during rapid step commands. The motor uses a NEMA frame size of 23, allowing installation in standardized motor mounts. Each full revolution consists of 200 discrete steps and provides a step angle of 1.8 degrees. Half-stepping produces a position resolution of 0.9 degrees, while microstepping can provide finer increments when supported by the drive.
The motor weighs 1.13 kg, making it suitable for small XY gantries while providing enough mass to help damp vibration. It operates at ambient temperatures from −20 to +40 °C, enabling installation in unconditioned factory spaces within this range. The shaft can support an axial load of up to 222 N and a radial load of up to 89 N, accommodating belt drives or moderate overhung pulleys without additional bearings. A rotor inertia of 0.0068 oz-in-s² balances rapid acceleration with step stability, while the two-stack arrangement supports the motor’s torque output. Thermal resistance between the winding and case is 2.62 °C/W. Continuous operation at rated current remains within the insulation limits when the housing is mounted to a metal plate that provides conductive cooling.
