Transmission
As previously mentioned, the electric motors are extremely powerful and may be rotated in either a
clock-wise or counter-clockwise rotation. For this reason, many people believe a transmission is not
required. But, reverse rotation is not optimal for the WarP Motor design, so having a transmission
allows for easy reversing of the vehicle as well as other advantages.
Direct drive applications also introduce a safety risk. If there were a catastrophic failure in the
electrical system that caused the motors to see full battery pack power, there would be no way to stop
the vehicle. The motors would have no problem overpowering the brakes, and unless a fuse blew or
a safety switch was successfully thrown, there would be no way of stopping the motors.
A transmission allows for a manual disconnect in extraordinary situations. Although the motors have
the torque to get the vehicle moving, they will draw far more amperage for a longer period of time
without a transmission. As with ICE engines, the motors have a sweet-spot where they like to
operate. This is normally in the 2,000 - 4,000 RPM range. The rule-of-thumb for these electric
motors is: the electric motors are most efficient when run about 1,000 RPMs higher per gear than the
ICE engine.
