<br> ## Inductors and motor driving ----- ### Inductors - ####Inductors are devices that store energy in a magnetic field. V= L*di/dt ![picture of symbol and examples](../images/inductors.jpg) ![picture of inductor circuit RL](../images/inductor_circuit.jpg) Figure: 1. Symbol and examples of inductors. 2. Inductor circuit. - ####driving inductive loads - flyback diodes. ![picture of flyback circuit](../images/flyback.jpg) ![picture of flyback circuit](../images/fet_flyback.jpg) --- ### Motor driver - ####To drive a motor, you need to be able to switch current direction. The usual solution is the h-bridge geometry. ![picture of h-bridges](../images/h_bridge_circuit_1.jpg) ![picture of h-bridges](../images/h_bridge_circuit.png) - ####Here is a module, and the chip that we will use to drive up to 3.5A of motor current. ![picture of h-bridges](../images/h_bridge_chips.jpg) ---
