AC Motors

The AC motor is the choice for more advanced conversions. It has the ability to operate larger vehicles than DC systems can, up to 3,500 lbs. factory curb weight. With its high rpm limit, the AC motor can be used without a conventional transmission for shift-free driving, or it can be coupled to a standard manual transmission. It provides regenerative braking to give dynamic braking action and recapture energy.

Solectria

Solectria has been manufacturing high quality AC drive motors specifically designed for use in vehicles since 1989. These AC motors have been primarily available to fleets and OEMs, but they are now available to the hobbyist conversion market, paired with Solectria control systems. The Solectria gearbox is a drop-in solution for direct drive in lightweight conversions.

Solectria motors feature:

• High efficiency brushless design
• Sealed motor casing
• Compact lightweight construction
• Low rotating losses
• Low electrical resistance
• High reliability
• 1 1/8" keyed shaft (on the AC24 only) for use with our taperlock adaptors, or splined for use with Solectria gearbox (AC24 only). The AC55 motor comes ONLY with the splined shaft and is used with our taperlock adaptors. We do not have a single-speed gearbox for the AC55.

These are integrated drive systems, with the motor, controller, and charger all custom configured at the manufacturer to fit YOUR conversion. For this reason, we need very specific information about your system to place your order.

Motor Ratings

It is not accurate to refer to a "10 hp motor" or a "15 hp motor", because horsepower will vary with volts and amps, and the peak horsepower will be much higher than the continuous rating. It is also confusing to compare electric motors to gas engines, since electric motors are given a continuous rating under load, and gas engines are rated at their peak horsepower unloaded. For accurate identification, a motor should be identified by name or model number.

The following chart gives specifications for the Solectria motors we carry. The AC24 motor is suitable for vehicles in the 2,000 - 2,400 lbs. factory curb weight (not gross vehicle weight).

The AC55 motor is suitable for vehicles up to 3,500 lbs. factory curb weight.
