6 Key Differences of Vertical & Horizontal Motors

Vertical motors can experience greater vibration than horizontal motors. That is because horizontal, foot-mounted motors are bolted to a solid base. With vertical motors, only the lower end is attached to a mounting flange, while the upper end remains unsupported. Most vertical motor vibration problems involve system resonance.
