Your micro-drive challenges are unique, and the ideas you put forward to solve them are unique. From medical to aerospace to security and access control, Portescap's brushed DC motor solutions drive life in key applications around the world. The following brushed DC motor section introduces our high efficiency, high power density, low inertia coreless brushed DC motor technology.
Why choose a brush DC motor
Innovation and performance
Portescap's brushed DC coreless motors incorporate a number of key technologies such as low moment of inertia, no cogging, low friction and a very compact commutation system that will result in faster acceleration and higher Efficiency, lower Joule losses, and greater sustained torque. Portescap's ironless motor technology reduces size, weight and heat, making it ideal for similar applications such as portable or small equipment. This results in superior motor performance in a smaller rack, providing end users with better comfort and convenience. In addition, in battery-powered applications, the coreless design also extends equipment life and increases energy efficiency.
Portescap will continue to optimize the configuration of magnetic circuits, self-sustaining ironless core coils and commutators, and continue to innovate for coreless technology.
Portescap provides fast samples and works with customers to engineer your products to get your products to market faster. Our R&D and engineering teams are able to adapt brushed DC coreless motors to encoders and gearboxes for superior performance in different configurations, environments and racks.
