Torque motors basics video: Construction variations and sizing and selection approaches
A torque motor is a direct-drive electric motor — usually of relatively large diameter — that applies torque to a driven shaft directly without intervening mechanics. Torque motors usually have higher pole-counts and run at lower speeds than servo motors – but they deliver much higher torque than standard servo motors. Some in industry liken […]
Frameless motor basics video: Operation, integration, and application
Frameless motors are rotor-and-stator subcomponent sets that aren’t prefixed in a traditional motor housing. They don’t include an output shaft (or shaft-support bearings) either. Instead, the OEM or design engineer works with the supplier to tightly integrate the frameless motor stator and rotor directly into the machine and framing. Watch this video for more: However, […]

Direct-drive motor designs: What variations are there?
The most basic definition of a direct-drive motor is a type of design that allows the motor to be connected directly to the driven load. Doing so eliminates mechanical transmission elements that tend to add compliance into a drive system such as gears, couplings, belts and pulleys, and chain drives. Direct-drive motors are sometimes also […]

Difference between drum motors and gear motors for food conveying
Traditional conveyor setups in food-processing and packaging industries use external gear motors as the belt-drive mechanism. But drum motors are increasingly common as an alternative conveyor drive. Here we review the strengths and weaknesses and potential improvements for both drive options. By Davide Barbanti, Associate Professor • Dr. Giampaolo Betta, Contract Professor in Food Science […]
