Electric Motors

We use powerful and efficient, liquid-cooled Permanent Magnet Synchronous Motors (PMSM) for our systems. These motors are designed for harsh environments, the high build quality ensures reliable operation for years to come. All motors come with an integrated controller and water pump. They are direct drive, the output shaft rotates at a suitable speed for most propellers, eliminating the need of a gearbox. All our electric motors are IP67, which means they are dust and water resistant.
