This component senses the speed input signal, integrates it to deduce the angular position, and uses this position along with an internal reference signal to generate amplitude modulated output signals that resemble those that would be generated by a typical sine-cosine resolver. This component is designed to be connected to the shaft of the machine components. It presents neither an inertial nor a frictional load to the shaft. 

The sine and cosine output signals are calculated as follows: 

Cos = A • sin(2πf) • cos(θ)

Sin = A • sin(2πf) • sin(θ) 


A = reference signal amplitude
f = reference signal frequency
θ = an internally calculated angular position

Connection Description
w_in, w_out (the shaft) The connection to the signal that carries angular speed in rad/s as a voltage.

Symbolizing a mechanical shaft, these two pins are internally short circuited; it does not matter which of the pins is connected to the speed signal. The secondary pin is available so that other mechanical components, external loads, sensors, or motion controllers can be chained and applied to the shaft, while maintaining the look of a rotary mechanical system.
cos+, cos- The differential cosine measurement.
sin+, sin- The differential sine measurement.

This component should only be used in transient-type simulations where Initial conditions are set to User defined.
