Electric Motors in Bicycles

Cheating in the sport of cycling has reached a “mind-blowing” new level, says 60 Minutes’ Bill Whitaker. There’s evidence that some professional riders are using bikes rigged with small, secret motors during races, a practice known in Europe as “motor-doping.

Whitaker and a team of 60 Minutes producers went to Budapest to meet Istvan Varjas, the engineer who says he invented the tiny bike motor, which he says has been used surreptitiously in the Tour de France.

The motor can be activated in several different ways: The rider can activate a secret switch on the handlebars, a partner can activate the system by wireless remote, or a heart-rate monitor worn by the rider can be programmed to automatically activate the motor when the rider’s heart rate rises to a certain level.

Multinational Grain Processing Company Experiences Repeated Bearing Failures – then Decatur Industrial Attacked

Before Decatur Industrial got involved, this large grain processing company had suffered two bearing failures in less than two years. They called us in to fix their 450HP motor, which was driving a large fan in their feedhouse, and they told us the story of their repeat catastrophic failures. They wanted to know why it kept happening!

Diagnosing the problem:  When we arrived on scene the motor was still in place running and our reliability specialist could hear bearing fluting as the motor had an audible howl to it.  With our SKF Arc meter and vibration analysis we verified the existence of electric current at both motor bearings and also at both driven fan bearings. Once the motor was able to be brought to our service center, we verified the bearings were indeed suffering from classic bearing fluting. Current discharge from voltage passing through the bearings as long been associated with large electric motors; however, the increased use of variable frequency drives (VFDs) has since resulted in shaft voltages in small low voltage machines.

The fix:  We insulated the ODE bearing housing and installed an AEGIS grounding ring – this motor has now been in place and running for four years with no subsequent bearing failures.  It operates noise free and vibration readings show no bearing issues. The customer has saved approximately $80,000 in repair costs over what they had been spending in repairs – plus no more downtime due to motor issues.
