About This Product
When the shaft speed brings the forcing frequency into line with the natural frequency of the system, resonance sets in. The speed at which this happens is the critical speed, also known as the whirling or whipping speed, and the dimmerstat lets students approach it gradually.
Frequently Asked Questions
What is a whirling speed?
It is the speed at which resonance occurs, when the natural frequency of the system coincides with the frequency of the external forcing. It is also called the critical or whipping speed.
How is shaft speed controlled?
A dimmerstat rated 240v, 2 amp, 50 cycles controls the speed of the 230V DC, 1/16 HP driving motor.
