Bought used with the intention of
converting. Ran perfectly well with the ICE.
MotorMars ME1004 Permanent Magnet DC
THE motor to use if you want to convert a
riding mower. This is a Permanent Magnet,
Brush Type, DC Motor with Neodymium Iron
Boron Magnets. The 1" shaft is similar to
the shaft on most Lawn and Garden Tractor
engines. This motor is perfect for an
engine replacement on a Lawn and Garden
tractor when converting the tractor to
electric propulsion. No motor control is
necessary for an engine-swap, but you will
need to add a Contactor, Fuse, and 48 VDC
batteries. Capable of 200 amps continuous,
and 400 amps for 1 minute. The efficiency
is 90%. MARS is now motoenergy.com
Controller None
Batteries4, 12.00 Volt, Lead-Acid, Flooded
The cheapest, Walmart Deep-Cycle Marine
batteries I could find - I'm going to do
everything I can to treat them right.
System Voltage48 Volts
Charger Harbor Freight 1.5A 3-Stage Battery Charger/Mainta
I took a chance and used 4 extremely
inexpensive chargers. They are permanently
connected and require approximately 36 hours
to recharge after I mow my lawn.
Top Speed5 MPH ( 8 KPH)
Faster than with the ICE.
RangeUnknown, but I can mow my 1/4 to 1/3 acre
and I still have a 90% charge.
Watt Hours/MileUsing a Kill-A-Watt I determined that I use
approximately 2.48KW to recharge after
mowing. We pay the most for electricity of
any city in the area, but it still comes out
to about 13 cents.
