To meet the demand for electrically driven pumps in the automotive, heavy truck, agricultural, and construction industries, MMT has developed a family of three-phase brushless dc motors delivering a respective 5 W to 1 kW of mechanical power in a three- and six-coil design. The motors feature a minimal design for low-cost manufacturing and offer improved performance including low detent torque without current, sinusoidal torque with current, high mechanical power per volume ratio, and high efficiency. Because the motors lack a commutation brush, the rotor can be directly immersed into a fluid, making the motors suitable for applications such as electric water, fuel, or oil pumps.
