Efficiency

Definition

Electric motor efficiency is the ratio between power output (mechanical) and power input (electrical). Mechanical power output is calculated based on the torque and speed required (i.e. power required to move the object attached to the motor), and electrical power input is calculated based on voltage and current supplied to the motor. Mechanical power output is always lower than the electrical power input, as energy is lost during conversion (electrical to mechanical) in various forms, such as heat and friction. Design of an electric motor aims to minimize these losses to improve efficiency.

Solution Overview

Portescap motors are designed to achieve up to 90% efficiency. Powerful neodymium magnets and enhanced magnetic circuit design enable our motors to reach stronger electro-magnetic flux, reducing electromagnetic losses. Portescap continues to innovate electro-magnetic design and coil technologies (e.g. coreless coils) that require low start-up voltage and consume minimum current. Friction is reduced and brush dc motor efficiency is improved by low-resistance commutators and collectors in brush DC motors. Our advanced design allows us to build motors with closer tolerances, narrowing the air gap between the rotor and the stator and resulting in less energy input per unit of torque output.

Portescap Technology

With advanced coreless coils and superior brush performance, our brush DC motors designs are highly efficient and are optimal for battery-powered applications. For high efficiency in high-speed applications, Portescap also offers a brushless DC motor design that is slotless, which significantly reduces joule losses.
