Bison Gear Adds 562 Series to FlexTorq™ Hollow Shaft Gearmotors

Versatile design offers opportunity to replace less efficient right angle worm gearing, while offering higher torque in a compact package.

Gearmotor and electric motor manufacturer, Bison Gear & Engineering Corp. has added 46 models of its 562 Series of hollow shaft offset gearmotors to its growing FlexTorq™ line of products. With a slightly larger footprint than a conventional right angle worm reducer gearmotor, the FlexTorq™ units provide from two to nine times more output torque, depending on the gear ratio utilized.

 

The 562 Seriesof FlexTorq™ gearmotors is offered in seven 115 volt, single-phase 1/20 hp (37.3 watt) versions and thirty nine DC versions with 12, 24, 90 and 130 volt inputs and powers of 1/8 and 1/20 hp (93.2 and 37.3 watts). Continuous output torques range from 66 to 1100 in-lbs (7.5 to 124.3 N-m), with corresponding fixed output speeds from 65 to 1.3 rpm.

 

"We find that special machine builders and OEMs really like the unique FlexTorq™ design because its offset parallel shaft configuration fits into a lot of tight spaces and it has exceptional torque density," said John Morehead, Bison Gear's vice president, strategic planning and marketing. "The fact that the hollow shaft units can be optioned with single or double output shafts in any of three diameters or fitted with one of our TightDrive™integral speed controls makes them truly versatile."

 

The FlexTorq™ gearmotorsare manufactured in Bison Gear's suburban Chicago facility to Bison's high quality standards in order to ensure a short supply chain and reliable, long-life operation. All the models of the FlexTorq™ gearmotors are supported by Bison's In-Stock, Instant-Ship (ISIS) program, which ensures immediate delivery of standard products. In addition, Bison's Innopreneurial™ application and design engineering capabilities to customize standard models to meet specific OEM needs are readily available.

10 Things Everybody Ought to Know About Custom Gearmotors

White paper details key considerations in making standard vs. custom decision with emphasis on maximizing overall lifetime value for electromechanical machinery and equipment designs. 

 

With heightened focus on budgets and time to market, engineers continue to face a quandary when designing new electromechanical machines and equipment: whether to design "around" a standard off-the-shelf gearmotor or to specify a custom gearmotor meeting their exact requirements. In response to growing concerns on this issue, Bison Gear & Engineering Corp. has analyzed its customer interactions and relationships and produced a new white paper covering the "10 Things Everybody Ought to Know About Custom Gearmotors".

 

"We've taken a non-Bison-specific approach in this white paper so that design engineers as well as OEM purchasing authorities will find it helpful, no matter what size or type of gearmotor they may use or who their supplier may be," said John Morehead, Bison Gear vice president, strategic planning and marketing. "The most important finding, drawing on nearly 50 years experience, is the necessity to involve one's gearmotor supplier's application engineers as early as possible in the design process. Inevitably, that ensures the best overall machine performance, durability and cost position."

 

Some of the other key issues covered in the white paper include the value of proprietary gearmotor specifications, reasonable lead time expectations for custom engineered prototypes, benefits of an expanding product portfolio, production scalability and value-added opportunities.

 

The new four-page white paper can be downloaded at BisonGear.com. 

Lean 2.0 Journey Highlighted in Bison Gear Video

Manufacturing scalability while maintaining customer satisfaction goals featured in new online video.

 

Rapid growth raises the specter of manufacturing scalability which, if not properly addressed, can quickly negate top line successes. A new online video highlights this challenge and how Bison Gear & Engineering Corp. responded to it to ensure that desired customer satisfaction metrics were achieved.

 

In the video, the gearmotor manufacturer's executive vice president, George Thomas, comments on Bison's "Lean 2.0" journey, which includes integration of demand planning and master scheduling to achieve level loading of the Illinois manufacturer's increased production capacity.   "At Bison, PRIDE means People Relentless in Delivering Excellence. To ensure customers receive that excellence, Bison developed a three-element PRIDE rating to measure customer satisfaction," said Thomas. "We're focused not only on overall on-time delivery percentage, but also the customer-centric metrics of change order acceptance rate and product approval rating in the field."

Bison Gear Receives "Healthiest Company in America" Award

Illinois manufacturer recognized for its commitment to employee health and well-being and its innovative health and wellness initiatives yielding measurable employee health improvement.

 

"Everyone talks about health care today, but more than a dozen years ago Bison Gear began creating a corporate culture that encourages individuals to take responsibility for their own health and to take an active role in their preventative care," said Bison Gear CEO, Martin Swarbrick. In recognition of the significant improvement achieved in overall employee health metrics, Bison Gear has received the "Healthiest Company in America" award from Interactive Health Solutions (IHS).

 

The award is based on clinical evaluations of employee participants across an index that tests for indicators of heart disease, diabetes, smoking and other measures of health status that are in part controllable by an individual. When Bison constructed its headquarters and manufacturing facility in St. Charles, Illinois in 1997, the gearmotor manufacturer budgeted for a completely equipped employee fitness center. More recently, it has invested in an onsite clinician ready medical resource center. In addition, a cross-functional team of Bison "Health Ambassadors" has been formed to develop and communicate health awareness and improvement programs throughout the company.

 

Working with IHS, Bison hosts an annual Wellness Fair for employees and their family members that includes free diagnostic testing and counseling. "Years ago, we were fortunate to win the business of an up and coming exercise equipment company," said Ron Bullock, chairman and owner of Bison Gear. "That customer relationship, which still endures, has contributed to the health of our business. More importanly, though, it made us more aware of the benefits of proactive health management and that has been an even greater contribution to every Bison associate."

Bison Gearmotor Plays Pivotal Role in Raising Funds for Charity

Windmill playhouse raises $10,000 at auction to help rehabilitate low-income and elderly housing

 

An elaborate playhouse featuring a Bison gearmotor powered windmill sold for $10,000 at auction, with one hundred percent of the proceeds used to provide free home repair services for the elderly and low-income homeowners in the San Francisco Bay Area. The "Molina of La Mancha" playhouse was designed by Topos Architects of Palo Alto, California, who selected a Bison Gear gearmotor to power the windmill on still days. The gearmotor Bison donated to the project is from the VWDIR23 series of right angle, variable speed drives.

The Don Quixote-inspired windmill was sold at the Dreams Happen auction which is the primary fundraiser for the Rebuilding Together Peninsula charity that provides free home repair services for those in need. The primary recipients of their services are senior citizens, single parents, grandparents raising grandkids, the disabled, low-income families with children, veterans, children caring for ailing parents and the sick or poor in health.  

 

"Bison Gear is always happy to support such worthy causes with product donations," said Sylvia Wetzel, Bison Gear chief learning officer and president of BisonCares. "After all, we're soliciting product donations for the silent auction portion of our 4th Annual Jeffrey Bullock Memorial Golf Tournament which benefits the Bear Necessities Pediatric Cancer Foundation and Lazarus House serving the homeless." 

"Although we sell gearmotors for special applications in the wind power industry and we also make permanent magnet dc motors that can be used as very small generators, I must say this is an application we did not anticipate," said John Morehead, who is Bison Gear's vice president strategic planning and marketing. "It's only one gearmotor, but the satisfaction everyone at Bison Gear received knowing the good work that will be done by Rebuilding Together Peninsula is as great as having sold thousands to an OEM."
