I have had the Better Place batteries on Craigslist for over a year with plenty of interest but no takers, so instead of selling the Fiero EV project, have been looking for a suitable AC motor replacement. While checking out Facebook, this new motor came up from Netgain.

NetGain HyPer9 AC Motor


Motor Face: B-Face (Warp Compatible)
Motor Diameter: 9.0 Inches
Motor Case Length: 13.75 Inches
Motor Shaft Length: 2.0 Inches
Motor Shaft to End Length: 15.75 Inches
Motor Type: Permanent Magnet Synchronous Reluctance AC
Weight: 90 lbs 
Max Voltage Input: 132
Terminal Stud Size: M8 Inch
Integrated Sensors: Encoder and Temperature
Rated Torque: 173 Lb Ft
Rated Power: 120 HP
Max RPM: 8,000
RPM Sensor: Yes
Drive End Shaft: 1-1/8 Inch with 1/4 Inch Keyway
Accessory End Shaft: Not Available (coming soon)
Max Efficiency: 0.94
Thermal Cooling: External Heatsink
Max Temperature: 150 Degrees Celsius

What draws me to this motor is the Low Voltage, HP, Torque, efficiency, and the fact that it is a direct bolt-in to the currently installed Warp9 motor. It is not available until November, but EV West has installed the motor in a conversion and has offered a test drive before purchasing the motor package. Also, George Hampstra has been very supportive of the EV conversion industry over the years and always had gifts for the attendees at EVCCON, along with drawings for motors and merchandise during the show, so I really want to support him! I always felt like the last couple of EVCCONs without George were just not the same.

Undoubtedly, I will have to spend more to get the Fiero back on the road than buying a used OEM EV but something about converting an older classic car is more appealing than driving a newer offering by an OEM.

Stay tuned!
