Brushless slotless motor

Portescap introduces the newest addition to its Ultra EC mini motor platform - the 16 ECH brushless motor, designed specifically to provide an economic motor solution for high performance applications.

The 16ECH has been optimised for high continuous torque at low to medium speeds, maximising power between 40K and 55K rpm, and rated speed at approximately 60K rpm.

The 16ECH provides high performance and is constructed with an enhanced high efficiency magnetic circuit that reduces both iron and recirculation losses, the primary causes for motor stator heating.

The new EC motor coil also achieves higher available torque and mechanical power compared to similar brushless motors. The result is the new 16ECH stays cooler and offers greater power density than equivalent models within its target operating zone.

The 16ECH offers an effective economic solution for high performance end applications by pairing the right amount of complexity, minimising motor size and optimising cost effective materials in its design. By optimising the electro-mechanical motor design and material selection of the 16ECH, Portescap succeeds in providing a high quality, long lasting, high performance brushless motor that is simple and efficient to operate.

The advantages of the 16ECH make it a great match for low speed, high torque end applications, or applications in the medium speed range (30 K to 55 K rpm).

The 16ECH is a good choice for geared applications because of its minimal speed drop and low motor heating under load. Additionally, the 16ECH’s efficiency, power density and long life make it an alternative for a brush DC motor solution. Lastly, the 16ECH’s low inertia design makes it an exceptional option for applications requiring fast stopping, starting and acceleration.

The 16ECH is available in 36 and 52mm length versions, with hall sensors and three different coils to match your speed and voltage requirements. Upon request, Portescap can provide options for customisation, including gearboxes, encoders, sensorless versions, coil variations, and mechanical interface modifications.
