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 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.

Specs:
