It is available with or without a 7/8" auxiliary shaft as well. This system is used in other vehicles that require the torque and horsepower that this motor supplies. It was designed for use in an automotive application with a curb weight of 4000 lbs or less. It is capable of producing 88 horsepower and 108 ft-lbs.

With the introduction of the new Curtis 144 volt controller we are now offering the AC-51 motor. Download Table Electric Motor HPEVS AC-20 specifications.
It is available with or without a 7/8" auxiliary shaft. It was designed for use in an automotive application with a curb weight of 3500 lbs or less. HPEVS AC12 Motor: 1: Curtis 1238-6501 Controller: 1: 35 Pin Connector and Wire Harness: 1: Gigavac GV200-QA Contactor: 1. In Part 1 of Best Electric Vehicle Motor Yet, we talked about the revolutionary HiPer AC-50, the Curtis 1238 controller that works so nicely with this motor.and most importantly, how can I get one of these great electric vehicle motors for my next conversion project, and what conversion shops are using these motors now.The AC 50 motor is an 8" motor that is capable of producing 71 horsepower and 120 ft-lbs. The AC-12 has across a variety of domains become a strong AC motor operating at 48-80V and drawing up to about 550A of power that produces about 37 HP and 86 ft-lbs of torque. Their have been simple 2 speed designs, but not a large enough market to be worth mass producing, at least not yet.Ī way to use an automatic transmission in a conversion has got to be right up there at the top of the EV crowd's letters to Santa, but it's still not a great idea at this point.
This is a better option, but it still has a lot of friction and looses inside that drastically reduce range.
HPEVS AC 50 MOTOR MANUAL
We have however converted a 2008 VW Jetta which uses a DSG transmission which is a manual transmission that is shifted with a computer. We have worked on theories to electronically control one of today's automatics but don't see much use for it. The Electric Vehicle Motor and the TransmissionĪ standard transmission uses only a couple HP to operate where an automatic uses 20 to 30 HP. With the AC50 our torque is flat until 3,500 RPM, the it starts dropping, so if you shift gears at 3,500 RPM you keep the motor right at it's sweet spot. High voltage allows the motor to run at higher RPM without loss of torque, some have just as much torque at 12,000 RPM as they do at 1,000 RPM. Slip is required to generate torque, but too much is bad. As you say, with higher voltage and AC control, there's no need to shift gears, torque can be accomplished with, what's it called - slip? And we know the high-voltage AC cars coming out now, like the Nissan Leaf, have what is basically a single-speed transmission. So.it seems like I remember that SW DC conversions have this different torque curve than an ICE standard transmission can really relate to, so people tend to lock them down to two gears, well, three if you count reverse. I don't want to give away the family secrets! I'm just trying to make sure I haven't misunderstood something. Most of our on road applications couple to the standard transmission, so shifting the gears helps with the acceleration. The higher the voltage, the easier it is to produce higher horsepower and torque, thus eliminating the need to shift gears. Yet, your AC 50 seems to turn that wisdom on its head, and 120v systems in light cars are quite snappy! So how did you do that? In part 2 of my interview with Brian Seymour from HPEVS, we talk about what size electric vehicle motor will best match your car, NEV. People who have tried to make AC conversions at lower voltages (120v-144v) end up with sluggish acceleration. I've heard that AC conversions work best at higher voltages, like 300v and up.
