WebThe Arduino Motor Shield is based on the L298 ( datasheet ), which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently. You can also measure the motor current ... WebControlling the V/Hz ratio applied to an AC motor controls motor torque. An AC motor develops rated torque when the V/Hz ratio is maintained. During acceleration (any speed between 1 Hz and 60 Hz), the motor shaft delivers constant torque because the voltage is increased at the same rate as the frequency. WebMay 20, 2024 · The proper way of controlling the speed of this type of motor is to vary the frequency of the supply using a device known as a variable frequency drive (VFD) or sometimes called an inverter. A light dimmer can't vary the supply frequency, it just changes the amount of each half-cycle that is fed to the load. gazelle hd
