High Speed Electric Motors
Torque Graphic

Speed of a motor may be the Drive Chain magnitude of the rotational velocity of the motor shaft. In a motion application, acceleration of the electric motor dictates how fast the axis rotates – the amount of total revolutions per unit time. Applications vary in their speed requirement, depending on what is being moved and the coordination with the various other components of the device. A balance should be achieved between rate and torque, as motors typically generate less torque when operate at higher speeds.

Solution Overview
We address speed requirements during our design process by creating an optimum coil (generally known as windings) and magnet configurations. In some styles, the coil rotates based on motor construction. Creating a motor design that eliminates the iron becoming combined with the coil results in higher speeds. The inertia of these high acceleration motors is reduced dramatically, increasing the acceleration (responsiveness) aswell. In some styles the magnet rotates with the shaft. Since the magnet may be the contributing aspect for the motor inertia, creating a different design from a typical cylindrical magnet is necessary. Decreasing the inertia drives higher velocity as well as acceleration.

Ever-power Technology
Ever-power has designed high rate 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 in comparison to brush DC motors with an iron-core style. Portescap offers a distinctive series of stage motors, the disc magnet series, which have a slim disc magnet instead of a cylindrical magnet. By reducing the inertia of the motors, we can achieve boosts to 10,000 rpm with a step engine, unparalleled in the market. Contact us today to observe how we will help you find the appropriate high acceleration motors for your motion-critical applications.
