摘要

A motor control system includes a variable voltage supply in signal communication with a direct current (DC) motor. The DC motor includes a rotor induced to rotate in response to a drive current generated by a variable supply voltage delivered by the voltage supply. The rotation of the rotor generates a mechanical force that drives a component. A ripple count circuit is configured to filter the drive current based on a rotational speed (ω) of the rotor, and to generate a pulsed output signal indicative of the rotational speed (ω) of the rotor and a rotational position (θ) of the rotor.

i = U a I a ,
can be calculated, e.g., by the controller 106, while the magnetic flux (Φ) of the motor 102, the number of winding turns (n) of the motor 102, and the number of motor slots (Sm) of the motor 102 are known constants. The inductance value (L) of the motor 102, and the motor constant (K) are also known constants. Therefore, the estimated rotor speed (ω) can be calculated as:

ω = U m - R i × I m - L ? d ? ( I m ) d ? t K × n × ?
