Product Description:

The PMX2320-C10-BN0-00 is a hybrid stepper motor produced by Kollmorgen within the PMX Stepper Motors series. As a two-phase motion device, it converts discrete current pulses from a drive into incremental rotary movement, enabling indexed positioning, velocity regulation, and straightforward open-loop control on packaging stations, pick-and-place axes, and compact conveyor modules. The winding is bipolar, and the coil set is arranged for two phases, providing predictable detent characteristics and straightforward driver wiring.

Internally, the motor’s stator-to-rotor geometry produces 200 full steps per revolution, so each electrical transition advances the shaft by a 1.8° step angle. A holding torque of 1.405 Nm keeps loads in position when excitation is maintained, which is important for vertically oriented tables or tensioning reels. The frame follows the NEMA 23 mounting pattern, allowing the unit to replace 57 mm square motors without altering brackets. The motor has a phase current of 1.24 A and a phase resistance of 6.20 Ω. These electrical values match the motor to low-voltage microstepping drives while limiting copper losses.

The case temperature is limited to 130 °C, so airflow or heat sinking must be provided when demanding duty cycles push the motor beyond continuous stall operation. The magnetic circuit uses a 2-stack rotor, adding axial length to increase torque density without changing the cross section. Field termination uses a 4-lead bipolar connection. With only two exposed coil pairs, phase identification is quick, and the risk of incorrect wiring is low. Mechanical coupling is handled by a smooth front shaft, which is suitable for press-fit pulleys or custom attachments. No rear shaft is fitted, helping keep the overall motor length compact. The motor is supplied without a shaft seal, so it is intended for dry environments where splash and particle ingress are not concerns.
