Product Description:

The PMX3430-A10-BK0-00 is a size-34 stepper motor produced by Kollmorgen as part of the PMX Stepper Motors series. As a two-phase device, it advances in discrete increments, making it suitable for positioning tasks in pick-and-place systems, small conveyors, and index tables that require open-loop motion control without feedback. Its purpose in industrial automation is to provide repeatable torque at low and medium speeds while keeping drive electronics simple.

This model delivers a holding torque of 1240 oz-in, helping the motor maintain load position at standstill. Motion precision comes from its 1.8 ° step angle, which divides one mechanical revolution into 200 equal increments. A rated phase current of 3.04 A matches bipolar drives that can supply constant current for accurate micro-stepping, while the phase inductance of 22.2 mH affects electrical time constants and drive-voltage selection. Environmental protection is limited to an IP30 rating, so the motor should be installed in clean, dry enclosures. The rotor uses a 3-stack laminated core, and the bipolar winding works with the 4-lead connection option to support series wiring. Additional electrical parameters include a phase resistance of 2.34 Ω at 25 °C and a thermal resistance of 1.35 °C/W, both of which are important for heat management during continuous operation.

The shaft can accept pulleys or couplings through an open keyway, and there is no rear shaft or shaft seal. The motor end bearings can absorb an axial load of 13.5 lb and a radial load of 49.5 lb without exceeding design limits. Overall housing length is 4.65 in, allowing direct replacement in NEMA 34 footprints. Operation is permitted at ambient temperatures up to 40.0 °C, so external cooling may be required if cabinet temperatures rise.
