Our standard range of electric vibrators are manufactured with either 2, 4, 6, or 8 pole winding configurations, to give fixed rotational speeds of 2880/3456 rpm, 1440/1728 rpm, 960/1152 rpm, 720/864 rpm respectively at 50/60 Hertz.

Invicta base-mounted rotary electric vibrator motors, sometimes known as unbalanced motors or shaker motors, are attached to pieces of vibratory equipment by either four, six or eight fixing points drilled into the foot of the motor.

Each frame size of electric vibrator motor has its own unique fixing locations and these dimensions are consistent across the range of products.
