The objective of optimized shaft alignment is to increase the operating life span of rotating machinery. To achieve this goal, components that are the most likely to fail must be made to operate ...

Linear motors are synchronous motors: Current is applied to the coil to form an electromagnet. The coil then synchronizes itself to the magnetic field generated by the permanent magnets in the magnet ...

All of the motors measure 21mm from front to back, plus 8mm of shaft protrusion. In each case there is a standard and a higher holding-torque variant, for example: the 42mm 200mNm HS17HX7L4100 and its ...

The linear voice coil motor (aka linear DC motor) is guided by a long-life plain bearing that can allow side loads up to 3 lb (13.5 N), while the precision ground 0.236-inch (6.0 mm) diameter shaft ...

This article was updated Feb. 20, 2023. It was originally published March 2, 2011. Engineers are constantly called on to select motors for the applications that will be able to do the task at hand and ...

NUM’s new TMX series direct drive motors have an extremely low cogging torque, making them suitable for applications that demand very smooth and accurate rotation, especially at low speeds. Typical ...

All major manufacturers of three-phase ac induction motors offer “inverter-duty” or “inverter-ready” models, but while these motors have inverter-rated insulation to protect the windings, the bearings ...

Brushless DC motors are common place in RC Vehicles. They are small, light, fast and can be inexpensive. [Raynerd] wanted a new spindle for his CNC machine and thought that a brushless DC motor would ...

O.G. Schmidt invented the electric trolling motor in 1934 when he attached the starter motor from a Model A Ford to a flexible shaft with a propeller on the end. A fanatical angler, Schmidt used the ...
