AC and DC motors work with EVs, but deciding which to use depends on your situation

During the
constant worldwide campaign to make the planet as clean as possible, electric vehicle (EV) drivers have
an improving chance of driving cars with fewer moving parts. One of an EV’s
greatest advantages is a quiet motor, which gives off an average of 100% torque
at zero RPM. But, if you’re going to make the transition to an EV, how do you
know what kind of motor will help your vehicle last the longest?

EVs use
either an AC or a DC
motor
, the difference between the two usually showing in how many volts at
which the motor can run. A DC motor will likely run between 96 and 192 V, while
an AC motor is probably a three-phase motor that runs at 240 V. According to How Stuff Works, DC
installations lean more on the inexpensive side, so they may be the better
option for someone still unsure about EVs but willing to try them. Usually
covering the 20,000- to 30,000-W range, DC motors also allow you to overdrive them,
meaning that a 20,000-W motor would briefly accept a higher wattage and
“deliver five times its rated horsepower.” The driver’s only concern would be
the building up of heat that too much overdriving can cause. If a driver
doesn’t push an AC motor too far, they shouldn’t have too much to worry about
in terms of longevity.

Advantages of a DC motor for anyone skeptical of
EVs also include more widespread
availability
and easy installation. One of the standout DC devices, the
DC Series wound electric car motor
, has a strong reputation partially
because it also works as a motor in electric drills. When it comes to cars, the
wound electric motor offers all of its torque from a standstill. Another
reliable source, the EV Photo Album,
cites the Advanced DC Serious wound motor as the most popular of its kind.

As for AC
motors, they’re usually more adaptable if a driver has a certain size, shape,
or power rating in mind, as they work with nearly any industrial three-phase
motor. Because of the AC motor’s regen feature, an EV’s AC motor can serve as a
generator and bring power back to its batteries. While a three-phase motor
relies on a DC power source, an inverter is present instead of a DC system’s
controller. An AC motor will handle rougher terrain more smoothly and allows
more acceleration. While this type is pricier, the benefits appeal to a wider
audience and could potentially help your EV last longer in general.

 

While
deciding which EV motor to use is largely a situational decision, both AC and
DC motors help lead to a healthier planet.
