Description

The Sinusoidal Torque Source block produces sinusoidal torque with a constant offset. A positive torque value generates torque acting from port B to port F.

The defining equation for the sinusoidal torque that the block generates is

$$T=T_o+A*\sin (2\pi ft+\phi ),$$

where:

• T is the output torque.

• T_o is the offset torque of the output.

• A is the peak amplitude of the sinusoid.

• f is frequency of the sinusoid in Hz.

• t is time.

• φ is phase shift of the sinusoid.
