Product Description:

The E32NRFT-LNN-NS-00 is a hybrid stepper motor produced by Kollmorgen and placed in the E Hybrid Stepper Motors series. As a two-phase positioning device, it converts digital pulse commands into fixed angular increments for indexing tables, pick-and-place actuators, and other automation axes that do not require closed-loop feedback. Its SIGMAX construction, NEMA 34 frame, and smooth shaft use standard mechanical interfaces, so it can be mounted in existing motion platforms. This open-loop format suits machines that rely on straightforward pulse control for repeatable positioning.

The motor delivers a holding torque of 659 oz-in (4.65 N·m), which helps it resist motion at standstill. Each pulse advances the rotor by 1.8 degrees; 200 full steps complete one revolution, so a controller can address discrete positions without microstepping. Positional error remains within ±1.5% of the commanded step angle for moderate repeatability requirements. Electrical integrity is supported by an insulation resistance of 100 Megohms and a dielectric rating of 340 Vdc, matched to its Class B, 130 °C winding system. Heat dissipates through a thermal resistance of 2.7 °C/W, allowing continuous duty in enclosures from −20 °C to +40 °C. Power is fed through a regular leadwire harness that provides a minimum conductor length of 12.0 in, arranged as an 8-lead set so the windings can be connected in series or parallel for low-speed torque. Two laminated stacks share a 3.76 in housing length, and the NEMA face mount uses a familiar hole pattern.

The shaft tolerates an axial thrust of 180 lb (801 N) and a radial overhung load of 35 lb, which can reduce the need for external bearings on light conveyors or belt drives. A rotor inertia of 0.0170 oz-in-s² supports rapid start-stop sequences without excessive overshoot, and the motor mass helps damp vibration during index moves. The assembly weighs 5.3 lb (2.40 kg) and fits into compact machine sections without adding excessive mass to the axis. These load and inertia characteristics support steady operation in compact positioning systems.
