High Speed Electric Motors
Torque Graphic

Definition
Speed of a engine may be the magnitude of the rotational velocity of the engine shaft. In a movement application, quickness of the motor dictates how fast the axis rotates – the amount of full revolutions per unit time. Applications vary in their speed requirement, depending on what is being relocated and the coordination with the other components of the device. A balance must be achieved between swiftness and torque, as motors typically generate less torque when operate at higher speeds.

Solution Overview
We address velocity requirements during our design process by creating an ideal coil (referred to as windings) and magnet configurations. In some styles, the coil rotates predicated on motor building. Creating a motor design that eliminates the iron becoming combined with the coil results in higher speeds. The inertia of the high swiftness motors is reduced dramatically, increasing the acceleration (responsiveness) as well. In some styles the magnet rotates with the shaft. Since the magnet may be the contributing factor for the engine inertia, developing a different design from a standard cylindrical magnet is required. Auto Chain Decreasing the inertia drives higher rate and also acceleration.

Ever-power Technology
Ever-power has designed high acceleration motors for our brushless DC and brush DC systems, with self-helping high-density rotor coils. The ironless nature of brush DC coils permits both high acceleration and higher speeds, especially compared to brush DC motors with an iron-core style. Portescap offers a unique series of step motors, the disc magnet series, which have a slim disc magnet instead of a cylindrical magnet. By lowering the inertia of the motors, we can achieve speeds up to 10,000 rpm with a step electric motor, unparalleled in the industry.
