Portescap, a leading expert in miniature motors and precision motion control solutions, recently unveiled the 20ECF and 32ECF brushless slotted flat motor, the latest addition to their motor portfolio. 

The 20ECF is characterized by a flat architecture, as well as a compact package size that is a hallmark of Portescap’s existing brushless motor portfolio. The motor’s 19mm rotor diameter is notably smaller than the 20mm diameter of competitive solutions.

The 32ECF motor has a diameter of 32mm and an overall body length of 17.6mm. With a 4-pole design and high-power density in a flat architecture, the 32mm motor utilizes an outer rotor configuration with an air gap between the coil and magnetic structure that is managed radially.

The 20ECF’s open architectural design ensures lower heating, and at fifteen grams, the 20ECF provides a mass savings of at least 30% when compared to other motion solutions. The motor’s design optimization also helps it achieve a 50% improved motor regulation factor relative to standard available solutions.

This 20ECF is an ideal choice for those looking for premium motor performance in an increasingly small package size. A variety of medical and industrial applications can realize the benefits of this motor, with it being particularly well-suited for surgical and service robotics, lab automation, premium tattoo machines, electric grippers, LiDar, and pumps.

The 32ECF motor’s electromagnetic circuit has been optimized for higher performance, with a 45% optimization of the motor regulation factor (R/K^2) as compared to standard available options. The motor also delivers a maximum continuous power of 32W at 10,000 rpm within a 32mm flat form factor, which is nineteen percent higher than many comparative solutions. As with any Portescap motor, options for customization abound.

The new 32ECF is an excellent choice for those working on next-generation projects, new programs, or future device iterations. The motor is best suited for applications that require a motion solution driven by performance but constrained by space, such as electric grippers, lab automation, infusion systems, service robots, and LiDar (Light Detection and Ranging).
