High Speed Electric Motors
Torque Graphic

Definition
Speed of a motor is the magnitude of the rotational velocity of the engine shaft. In a motion application, rate of the motor dictates how fast the axis rotates – the amount of total revolutions per unit period. Applications vary within their speed requirement, depending on what is being moved and the coordination with the additional components of the machine. A balance must be achieved between acceleration and torque, as motors typically generate much less torque when run at higher speeds.

Solution Overview
We address rate requirements during our design process by creating an the best possible coil (referred to as windings) and magnet configurations. In some styles, the coil rotates based on motor building. Creating a motor design that eliminates the iron becoming combined with coil results in higher speeds. The inertia of these high velocity motors is decreased dramatically, raising the acceleration (responsiveness) aswell. In some styles the magnet rotates with the shaft. Because the magnet may be the contributing aspect for the motor inertia, developing a different design from a typical cylindrical magnet is necessary. Stainless Steel Chain lowering the inertia drives higher acceleration as well as acceleration.

Ever-power Technology
Ever-power provides designed high speed motors for our brushless DC and brush DC technology, with self-helping high-density rotor coils. The ironless nature of brush DC coils allows for both high acceleration and higher speeds, especially compared to brush DC motors with an iron-core style. Portescap offers a distinctive series of stage motors, the disc magnet series, that have a slim disc magnet as opposed to a cylindrical magnet. By lowering the inertia of the motors, we can achieve speeds up to 10,000 rpm with a step engine, unparalleled in the industry. E mail us today to observe how we will help you find the appropriate high speed motors for your motion-critical applications.

Ever-power high acceleration motors are perfect for the following applications:
Respiratory and ventilation devices
Laboratory automation
Miniature pumps
Power hand tools
Yarn guides
Barcode scanners
