Instantaneous value for an angle
Calculator for the current value of a sinusoidal oscillation at a certain angle
On this page you can calculate the instantaneous value of a sinusoidal oscillation at a certain angular position.
The voltage can be entered as an effective or peak value. The angle can be selected between degrees and radians.

Formula for calculating the instantaneous value
When a rotor rotates uniformly in a homogeneous magnetic field, the induced voltage changes sinusoidally. If the peak value û is known, the instantaneous value can be determined from the angle.
\(\displaystyle u=û · sin(α)\)
