There are two main types of vibration motors,
eccentric rotating mass (ERM) and linear resonance actuators (LRA).
LRAs require a very specific resonant frequency
and an AC drive signal for optimal operation,
so this article will focus only on ERMs.
An acceptable vibration level would be below
0.16 in/sec (pk) or 2.8 mm/sec (rms). Restricted
Operation – the same motor/pump operating
a vibration levels between 0.16-0.25 in
/sec (pk) or 2.8-4.5 mm/sec (rms)
should be considered to have a problem
causing excessive vibration, such as unbalance or misalignment.
Powerful Vibrator Motor -
TOAUTO Concrete Vibrator supports 30/40/50/60/70/80/90/100W
series motor for your choose. 110V AC Single Phase 3600 RPM,
powerful and durable. High Quality - Aluminum Alloy Case,
which is light weight and fast heat dissipation while being robust and durable.
They are typically coin form factor,
8 ~10mm diameter and 2 ~4 mm thick.
BLDC vibration motors are available in similar
sizes as the brushed ERMs, although
the range isn't quite as expansive.
