ETK-ETEKBL90 Mars Brushless PMAC Motor with 90A Controller Kit <p align="left"><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">Get
monstrous power from this motor! </font><font color="#00FF66" size="2" face="Arial, Helvetica, sans-serif">Originally
designed for Briggs &amp; 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.</font></p>
<p align="left"><font color="#00FF66" size="2" face="Arial, Helvetica, sans-serif">This
is the 90A controller kit, it DOES NOT support regen. The
<a href="ETK-ETEKBL250.html">250A controller kit</a> supports regen, which
means it 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!</font></p>
<p><font color="#00FF66" size="2" face="Arial, Helvetica, sans-serif">This motor
is a direct replacement for the Etek (Briggs &amp; 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.</font></p>
<p><font color="#00FF66" size="2" face="Arial, Helvetica, sans-serif">Commutation is accomplished with an internal Hall Cell assembly, connected
to the 6-pin external wire harness.</font></p>

<p><font color="#00FF66" size="2" face="Arial, Helvetica, sans-serif">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.</font></p>
