Motor Controller
A dual DC motor controller employs an H-bridge controller chip. In addition to the standard features of the H-bridge driver chip, such as thermal and over-current protection, the circuit supports dual 12V/5V regulated power supplies, sign/magnitude and brake driver logic,...
Need Help Deciphering Circuit Board Schematic
The wire speed DC motor consistently receives approximately 20 volts, irrespective of the switch position on the nozzle handle. The switch has been tested with an ohmmeter and functions properly. Even after disconnecting the switch from the circuit board, the...
The 4Q2 DC Motor Speed Controller Circuit and Datasheet
This figure represents the 4Q2 DC Motor Speed Controller Circuit Block Diagram, designed for comprehensive control of conventional shunt-wound and permanent magnet motors with a capacity of up to 75 kW, as specified in the datasheet. This type of DC...
Bidirectional H-Bridge Monitoring with ADC-Friendly Differential Output
The dual outputs of the LTC6103 can be utilized independently for overload detection or combined as a differential pair to provide a bidirectional signal to an analog-to-digital converter (ADC). A typical circuit for a generic H-bridge application is illustrated. The...
DC Motor-Driver H-Bridge Circuit
Physical motion of some form helps differentiate a robot from a computer. It would be nice if a motor could be attached directly to a chip that controlled the movement. But, most chips can't pass enough current or voltage to...
DC motor speed control
The circuit utilizes a 4011 CMOS NAND gate, a pair of diodes, and an NPN power transistor to create a variable duty-cycle DC source. By adjusting the speed control, the average voltage applied to the motor can be varied, while...
