The 80MPH series stepper motors with an 86mm flange, as well as the
56mm 80MPD series motors are said to be among the most powerful motors
currently available on the market in regard to holding torque and
length. Equipped with an aluminum housing, the NEMA 34 motors are able
to transport thermal power dissipation with low thermal resistance,
reducing motor heating and increasing bearing lifespan. The stepper
motors can be delivered with or without an encoder system. B&R Industrial Automation Corp.www.br-automation.com770.772.0400
