PMX2320-C10-BN0-00 by Kollmorgen

Kollmorgen manufactures the PMX2320-C10-BN0-00, a stepping motor in the PMX Stepper Motors series. As a discrete-increment actuator, it converts pulse trains from a drive into precise angular movement, allowing indexing tables, labeling heads, or small pick-and-place axes to position loads without closed-loop feedback. This operating method suits compact machines that rely on commanded pulse counts to establish position and repeat short travel moves. A NEMA 23 frame mounts directly to standardized 56 mm faceplates in linear stages and gearheads.

The motor develops 1.405 Nm of holding torque, so the shaft can maintain position against static loads when the phases are energized. Each revolution is divided into 200 full steps per revolution by the internal rotor-stator geometry, and microstepping drives can subdivide those increments further for smoother motion. The intrinsic 1.8° step angle simplifies motion calculations because every ten pulses move the output 18°. Electrical losses are limited by a 6.20 ? phase resistance, which affects the voltage needed to reach rated current and influences thermal rise during continuous dwell.

In operation, the coils draw 1.24 A per phase, matching mid-range microstepping drives that prioritize low heat generation over high slew rates. The stator is wound in a bipolar configuration and brought out through a 4-lead bipolar connection, enabling direct connection to compatible drives. A 130 °C maximum case temperature sets the thermal ceiling, so adequate airflow or heatsinking must keep the housing below this limit. Mechanical layout favors compact assemblies: the smooth front shaft eliminates key stress risers, the rotor uses a 2-stack rotor to boost torque without extending frame width, and no rear shaft is supplied, allowing the back face to mount directly against panels. The smooth front shaft also simplifies coupling to hubs or pulleys that clamp directly to the motor output. The two-phase design and the absence of a shaft seal suit standard indoor automation environments.
