Podium finish at TT Zero for Parker Hannifin-powered bike
A prototype electric motorcycle powered by a motor developed by Parker Hannifin has taken third place on the podium at this year’s SES TT Zero Challenge on the Isle of Man.
The TT Zero event, established in 2010, is a race for motorcycles powered without the use of carbon-based fuels.
The Victory Racing team’s prototype bikes, ridden by “General” Lee Johnston and road racer and television presenter Guy Martin, took third and fourth spot respectively in the all-electric race.
The prototype electric motorbikes, powered by Parker Hannifin’s Global Vehicle Motor (GVM) PMAC electric motors, weigh just 220 kilograms each, and are capable of average lap speeds approaching 120mph.
Despite measuring just eight inches in diameter and five inches long, the GVM motor can deliver 175 horsepower, and has an efficiency of 97 per cent.
To develop a device that could generate a large amount of torque, and therefore power, for its size, the company designed a 12 pole motor, referring to the number of sets of North-South electromagnetic poles formed by the magnetic windings. The more poles a motor has, the greater its torque will be.
