Where do I find the AC motors that are used to run the mower blades that
are on the decks of the riding mowers like Recharge n Zeon hustler etc.
I looking for myabe 750, 1000 watt motors.
Are you sure they're using an AC motor? Every electric mower I've seen
used plain old brushed DC motors. Either it's running directly on the
battery (like my ElecTrak, or Black & Decker push mower), or it's
running off the AC line with a bridge rectifier (my Rally mower).
Also whats the differance between Dc brushless and Ac motor?
Fundamentally, they're both AC motors. *All* motors are really AC motors!
- A brushed DC motor uses brushes and a commutator to convert DC
into AC for the actual motor. Brushed motors can either
use magnets or wound field coils.
- A "brushless DC" motor is just an AC motor with an electronic
commutator ("inverter") to convert DC into AC for the motor.
Most (but not all) brushless DC motor have permanent magnets.
- An AC motor obviously just leaves off whatever device the others
had to convert DC into AC, since AC is already available.
Most (but not all) AC motors don't use magnets.
AC is 3 phase and Dc brushless has electronics on the motor that changes
it to AC?
Not quite. AC motors can have any number of phases; single-phase,
2-phase, and 3-phase are the most common.
The controller (for any type of motor) can either be attached to the
motor, or in a separate box.
