The first version of this 3D printed PCB motor used press-fit bushings and a metallic shaft. While this worked, ... The next step is closed-loop control of this motor.

Over the last 2 years [Carl Bujega] has made a name for himself with his PCB motor designs. His latest adventure is to turn it into a stepper motor by adding position control with microstepping. Th… ...

When it comes to position control, the choice is often between a stepper motor and a servomotor. Because stepper motors typically have more poles than servomotors, they produce a lot of torque for ...

Motor control circuit conductors tapped from the motor branch circuit protection device that extends beyond the tap enclosure must have overcurrent protection, as shown in the Table. The above ...

For example, traditional step motor systems run in open loop control. That means the drive electronics continuously supply current to the motor whether or not the load is demanding torque.

Our first idea was to take a phase-frequency detector type of phase-locked loop (PLL ... Q1, performs as a chopper to power the dc motor. The circuit ... Smart System for Motor-Drive Control.

Along with a dsPIC33 digital signal controller (DSC), motor drivers from Microchip pack a three-phase MOSFET gate driver and optional LIN or CAN FD transceiver. These integrated devices reduce the ...

The multimeter shown in the Figure helps depict the troubleshooting steps used to isolate problems in the control circuit. One multimeter test lead (typically the black for consistency) is placed at a ...

In Part 1, we’ll discuss some general recommendations for designing PCBs that use motor-driver ICs, which require special cooling techniques to handle the power dissipation. Printed-circuit ...
