• 18 Horsepower and 81 Foot Pounds of Torque • 6000 RPM Motor • 25 MPH without Gear Change • Full Regenerative Braking to zero speed • Higher Torque, Lower Power Consumption • Fits Club-Car, EZ-Go, Yamaha, Columbia Par-Car, or any Graziano or Dana- Spicer Differential • No brushes or commutator • Golf/Street mode switch • Zero to 20 MPH in under 3 1/2 seconds!

“We’ve really branched out,” says Brian Seymour, co-owner, “expanding from the golf car after-market industry into customized AC motors for a wide range of industrial and utility vehicles. Electric motors are so environmentally friendly, they’re becoming more and more of a popular solution. We’re designing electric drive systems for light industrial and utility vehicles that are used in so many applications, from seaports, airports, military bases, postal services and municipalities to private communities and university campuses. We’re also designing AC drive systems for small flatbed trucks that can carry up to 1,000 lbs. There’s a lot of opportunity in the AC market that we’re really just beginning to explore.”

AC motor technology is ideal for conversion of golf cars because it provides: • Cost economy • Variable speeds • Fewer parts – less maintenance • Energy efficiency – longer battery life • Less downtime for charging and repairs • Precision control • Improved acceleration • Cooler running • Easier troubleshooting, with onboard self-checking • Suitability for a wide range of applications, including heavy duty and demanding environments
