Portescap introduces the16ECP motor, the newest addition to the Ultra EC™ brushless slotless motor platform. The Ultra EC platform currently includes the 22ECS motor, a 22 mm diameter motor available in 2 lengths, which is specifically optimized and tailored for respirator applications. All products from the Ultra EC platform share a best in class magnetic circuit that provides exceptional efficiency and design flexibility to allow the Ultra EC platform to be optimized for exact customer working points.
The 16ECP is an excellent choice for many BLDC motor applications, especially applications requiring high efficiency and long life. This is because the 16ECP, a 16 mm diameter brushless motor, can be adapted and optimized to meet a wide range of different torque and speed working points.
The Ultra EC coil, the heart of this motor, makes it possible to lower the amount of power losses (Joule losses and iron losses) for a given working point to a minimum. Taking advantage of this technology, engineers designed the 16ECP to achieve the following BLDC motor performance:
- optimized for low to medium speeds
- impressive maximum continuous torque at low speed (for a 2 pole motor)
- maximum power between 40 K and 55 K rpm
- maximum rated speed around 60 K rpm.
The 16ECP performance results are achieved using the right amount of complexity, minimizing motor size and avoiding use of expensive materials to make the 16ECP both high performing and economical. The 16ECP embeds customary Portescap quality design standards for bearings, electronics, and assembly, to ensure motor reliability and long life.
Lower speed applications, such as applications using gears, or the redesign of applications that previously used brushed DC motors, are ideal uses for the 16ECP coreless BLDC motor with these technology advantages. For medium speed applications, the 16ECP’s impressive figures of merit will result in lower speed drop and lower heating under torque.
The new 16ECP motors are available in 36 and 52 mm length (16ECP36 and 16ECP52 respectively), with hall sensors and 3 different coils each to match your speed voltage requirements. Contact your local Portescap representative for customization possibilities such as gearboxes, encoders, sensorless versions, different coils, or any mechanical interface modifications.
