Available in NEMA 23, 34 and 42 frame, both H and E Series are high efficiency, low loss hybrid step motors in conventional (round frame) configurations. A selection of industry standard windings and standard options assure the best motor for your application with holding torques up to 4276 oz-in. Select from terminal board connections (via conduit), MS connectors or flying lead connections in waterproof or standard enclosures. Options include shaft keyways or flats, oversized drive shaft, rear shaft extensions and various encoder options. Bipolar or unipolar phase sequencing is also available. PacSci will also work with you to design custom features as an economical solution to your application specific requirement.

Our general purpose hybrid steppers allow you to tailor a motor to your in-plant or OEM application. Select from an array of capabilities to optimize your motion requirements. From common "workhorse" applications to your most demanding velocity and positioning requirements. For increased torque and acceleration, E Series general purpose motors feature our patented Sigmax(R) technology. Both H and E Series motors provide the high speed capability required for rapid traverse applications.

Unequaled in performance, Pacific Scientific hybrid step motors have the highest torque per frame size in the industry. A rugged space saving enclosure plus a host of options mean these hybrid steppers offer industrial design, industrial quality and industrial performance for your application.
