DC Motors - Torque and Speed
DC Motors - Torque and Speed
In this video, we learn about the motor 'velocity constant', which relates motor voltage and speed. We write some code to experimentally determine the motor velocity constant using just one data point by setting motor voltage to 5V and reading the speed from the encoder.
In this video, we revise our motor velocity constant by testing the motor at many voltage levels. In order to accomplish this, we learn how to use 'pulse-width modulation (PWM)' to allow a digital pin to produce effectively analog voltages.
In this video, we learn how to wire up a motor driver chip to provide higher current to our DC motor, but still control the velocity with the PSoC. Then, we learn about the motor torque/speed curve, and how we can use this curve to spec motors for an application.
