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 ...

High vibration is a common problem for motors installed on top of vertical pumps. Its source can stem from a mechanical issue with the pump, motor, or coupling — or even hydraulic forces from the pump ...

Interfacing a shaft to a 3D printed gear doesn’t have to be tricky. [Tlalexander] demonstrated a solution that uses one half of a spider coupling (or jaw coupling) to create an effective modular ...

WILMINGTON, Mass., Aug. 12, 2025 /PRNewswire/ -- Stafford Manufacturing Corp. has introduced a new line of shaft collars, flange collars, and rigid couplings offered in large sizes for building and ...

Engineers and designers commonly use electric motors to power hydraulic pumps. In some cases, the motor and pump are set up in a direct drive configuration. In others, they are connected using an ...

A big reason step motors stall is that they don’t have enough additional torque to overcome resonant motor shaft vibration. Find out what causes resonance and the most effective ways to damp it. One ...

The vast majority of bearing failures in electric motors and electric motor-driven equipment are due to mechanical and thermal causes. However, currents that flow through induction motor bearings can ...

These days, it’s common among us hackers to load a stepper motor with forces in-line with their shaft–especially when we couple them to leadscrews or worm gears. Unfortunately, steppers aren’t really ...
