Torque Source
A source of mechanical energy that generates torque proportional to the input signal.
Description
The Torque Source unit represents a mechanical energy source that generates torque proportional to the input signal.
Connections R and C represent mechanical rotation conservation ports. The S port is the signal that controls the source. You can use the full variety of signal sources to create the desired torque profile. A positive signal on port S creates torque acting from C to R. The torque generated by the source is directly proportional to the signal on the S control port.
The positive direction of the block is from port C to port R. This means that the torque is positive if it acts in the direction from C to R. Relative velocity is measured as , where , are the absolute angular velocities at ports R and C respectively, and it is negative if the velocity at port R is greater than that at port C. The power generated by the source is negative if the source supplies power to port R.
Ports
