POWER TRANSMISSION REFERENCE
GUIDE
These outer-rotor brushless motors from Allied Motion Technologies are designed for hightorque, low-cogging applications like robotics, AGVs, and handheld power tools. The KinetiMax High Power Density (HPD) motor series feature an efficiency rating of over 85% coupled with a high power-to-weight ratio. They’re available in six frame sizes, with three stack-lengths per size and three windings per stack length.

electric motors THERE
are many types
of electric motors used in power transmission. They vary from small brush dc motors for moving light loads to high horsepower ac motors powering conveyor lines in heavy duty mining applications. For more precision applications, servomotors and stepper motors are the motors of choice. Here, compact size and high torque as well as greater controllability are common advantages.

DESIGN WORLD — MOTION
Electric motors can be categorized in a number of different ways; as ac (alternating current) or dc (direct current) motors, or by the type of motion they produce, rotary or linear. Another common approach is to distinguish between commutation methods; for example, self-commutated or external, and by mechanical means (as brushes used in brushed dc motors) or electronic commutation (as in brushless dc motors.)
MOTORS – AC There are two fundamental types of ac motors; induction and synchronous motors. 5 • 2020
Induction motors run at constant speed across a wide range of load settings, from zero to full-load. With synchronous motors, their name indicates that they run synchronously with the frequency of the source. The motor speed is fixed and doesn’t change with changes to the load or voltage.
MOTORS – DC A dc motor works by generating a magnetic field via electromagnetic windings or permanent magnets. The most common industry naming conventions for dc motors recognize three subtypes: brush motioncontroltips.com
