Get
monstrous power from this motor! Originally
designed for Briggs & Stratton
4.5 HP continuous outboard boating applications. Brushless Permanent Magnet
Synchronous motor otherwise known as PMAC motor. Input voltage of 30-72 VDC.
100 amps continuous, up to 300 amps for 30 seconds. The phase resistance
is very low at 10 milli-ohms, so it is 90% efficient. This motor has a built-in
cooling fan set for a CCW direction, but can be run CW with optional fan.
Motor weight is 22 pounds.
This
250A controller kit supports regen, which means this system can recapture
rotational energy and recharge the battery pack. In the case of being used
to power a prop on a sailboat, under a heavy sail or anchored with a strong
current a boat with this system can be generating power off a dragging prop.
There are many uses for this system!
This motor
is a direct replacement for the Etek (Briggs & Stratton) brushed
DC motor. It is an Axial Air Gap permanent magnet motor. This technology is
very compact. Highest potential power to weight ratio of any PM motor technology.
Commutation is accomplished with an internal Hall Cell assembly, connected
to the 6-pin external wire harness.
Output Power, Torque and RPM:
Voltage Constant: 70 RPM/VDC. Torque Constant: 1.20" lbs/amp. Max Motor
Current: 300 A/1min. Weight: 22 Lbs. Dia. 8". Output: 15HP Max. 6HP Cont.
Voltage: 24-48 VDC.
Due
to the high RPM of this Brushless motor, we recommend using a gear
reduction system rather than direct-drive. This will improve efficiency,
provide proper torque and cooling, and prevent cavitation.
