Product Description:
The E32NCHP-LNF-N8-02 hybrid stepper motor is produced by Kollmorgen for the E Hybrid Stepper Motors series. Designed for incremental motion control, it converts command pulses from a microstepping drive into repeatable shaft positions without the need for an encoder. Manufacturing cells use this motor to index conveyors, advance packaging film, and position light machining fixtures where its compact size and consistent step accuracy simplify the control architecture.
The motor occupies a NEMA 34 frame and delivers up to 673 oz-in of holding torque. Each winding is rated for 8.1 A and has 0.19 Ω of phase resistance with 2.2 mH of inductance, allowing a fast current rise from low-voltage drives. A standard four-lead parallel connection terminates in a System MS connector, and SIGMAX construction concentrates magnetic flux for high-speed output. The 1.8° step angle provides 200 full steps per revolution with ±1.5% accuracy. Thermal resistance of 2.7 °C/W supports forced-air cooling, while Class B insulation rated for 130 °C, insulation resistance of 100 MΩ, and a dielectric rating of 340 VDC protect the coil system. Two rotor-stator stacks and a rotor inertia of 0.0170 oz-in-s² support a winding optimized for maximum torque at high speed.
A smooth shaft transmits motion and tolerates an axial load of 180 lb and a radial load of 35 lb without excessive bearing stress. The motor operates from -20 °C to +40 °C, making it suitable for unconditioned enclosures, and its total mass is 5.3 lb, which eases installation on lightweight gantry axes. The NEMA mounting face aligns directly with standard gearboxes, while the latched MS connector resists vibration. Adequate airflow helps control winding temperature during continuous indexing applications. The smooth shaft can connect to compatible clamping couplings used in conveyor, packaging, and positioning assemblies.
