Circuitry (e.g., 7, 9) for controlling motors (e.g., Figs. 2A and 2B), such as a brushless motor (BLM). is disclosed. The circuitry (e.g., 7, 9) may comprise one or more inputs for receiving rotor position signals (e.g., 91, 92) from one or more Hall effect sensors (e.g., 3) that detect the position of, for example, a BLM rotor (e.g., Figs 2A and 2B). The circuitry (e.g., 7, 9) may also comprise an input for receiving a pulse width modulated speed control signal (e.g., 114, 320). The circuitry (e.g., 7, 9) generates one or more drive signals (e.g., 322, 324, 326, 328, 41 -42, 43-44, 41 -42 (PWM), 43-44 (PWM)), each of which may comprise a Jogicai combination (e.g., a logical AND combination) of the speed control signal (e.g., 114, 320) and a rotor position signal (e.g., 91, 92), for controlling power switches (e.g., F1-F8) that are coupled to electromagnets of the BLM (e.g., Figs. 2A and 2B). |
