Bison's shaded pole gearmotors offer fail-safe disc brakes
Many OEM applications require the use of a fail-safe brake, which operates on the power-"off", brake-"on" principle. To fulfill that requirement, Bison Gear and Engineering Corp. unveils the fractional-horsepower parallel-shaft VWDIR08 and VWDIR88 gearmotors with unidirectional shaded pole motors. Designed as Von Weise drop-in replacements, the Bison VWDIR08 and VWDIR88 gearmotors are available in 14 standard models. With gear ratios from 27:1 to 750:1, fixed output speeds range from two to 60 RPM, with output torques from 42 to 113 in-lbs. The Bison drop-in replacements for VW08 and VW88 gearmotors feature UL and CSA recognized 1/10 and 1/20 hp shaded pole motors with clockwise rotation and 115 Volt, 60 Hertz input as standard. The gearmotors are grease lubricated for long life and all-position face or foot mounting with a 150-pound overhung load rating. The shaded pole electric motors can also be speed controlled with a simple, inexpensive triac drive. Bison's VWDIR08 and VWDIR88 gearmotors are supported by Bison's Innopreneurial application and design engineering capabilities to customize standard models to meet specific OEM needs. The VWDIR08 and VWDIR88 AC gearmotors are part of the expanding Bison Gear line of Von Weise drop-in replacement gearmotors, which encompasses over 75 standard models.
