Product Description:

The CTP33NLF47KAA00 is a hybrid stepper motor manufactured by Kollmorgen as part of the CT Stepper Motors series and the Cool Torque Performance family. It is driven in bipolar mode and converts step pulses into precise angular motion for positioning tables, metering pumps, and other indexing axes used in industrial automation. A size-34 frame combined with a three-stack lamination lets the motor deliver elevated torque density where servo feedback is unnecessary but repeatable open-loop control is still required.

The motor produces a continuous pull-out torque of 11 N·m when powered by a bipolar drive. Each phase must be supplied with 4.7 A, so the drive electronics and conductors have to accommodate that current. Bearings can withstand an axial load of 100 lbs in either direction, allowing direct coupling to lead screws or thrust collars without auxiliary supports. The size 34 housing, which is about 85 mm square, matches standard NEMA mountings while enclosing three laminated stacks for higher flux. Insulation is rated to 340 VDC, providing headroom for drives that operate from elevated bus voltages to achieve rapid current rise times. The unit follows a bipolar excitation scheme, is furnished with four separate leads, and dissipates heat through the Cool Torque Performance construction.

Mounting is through NEMA through holes, so the frame bolts directly to machine plates. A straight keyway on the shaft simplifies keyed coupling, and bearings handle up to 65 lbs of radial load at the shaft center before life reduction occurs. The lamination assembly is a 3-stack design that supports the high-torque characteristic highlighted by Kollmorgen. The rear end is left open with no accessory hardware, and the four-lead wiring exits as unshielded pigtails for quick connection to standard bipolar step drives.
