DC Motor Speed Controller Circuit
This motor speed controller utilizes a single IC, the LM1014, to regulate the speed of a DC motor. It detects the increase in motor current as the rotation of the motor increases.
The motor speed controller is designed around the LM1014...
Stepper Motor Generator
Any stepper motor can function as a generator. Unlike other types of generators, a stepper motor generates a significant induced voltage even at low rotational speeds. The specific model used here has a DC resistance ranging from 2 ohms to...
Controlling Stepper Motors Using Power IO Wildcard MOSFET Driver
For optimal efficiency, set MAX_STEPPERS to the number of stepper motors being controlled, with a maximum limit of four. Motors are identified by indices 0, 1, 2, and 3. On the QCard, there is a trade-off between the number of...
sn754410
After testing the motors, a current draw of up to 1.3 Amps was observed. Two SN754410 H-Bridges were stacked, and a heat sink was constructed from an aluminum can. This setup should handle 2 Amps or more. The heat sink...
TB6560 Stepper Motor Driver Boards
Attached are three captures from a L297/L298 board using the same motor at 500, 750, and 900 steps per second on a 36V supply, wired in bipolar parallel (coil resistance = 3.2 ohms). This shows the A-enable signal (blue) and...
Driving a Capacitive Load with an H-bridge
Following the publication of a previous post, some unusual issues were encountered, which required several days to clarify. The main focus was on building a simple Class D amplifier designed to provide an EL panel with a +/- 120V square...
H-Bridge (A2060H) Manual
The A2060H is an H-Bridge extension for the Programmable Logic Head (A2060). Utilizing an external power supply to deliver motor current, the A2060H enables variable-speed, bi-directional control of DC motors. These motors can operate within a voltage range of 6...
Computer Controlled Stepper Motor
This article outlines the process of connecting a stepper motor to a computer's parallel port and writing code to control it using the scroll wheel of a mouse. For those unfamiliar with stepper motors, this project offers an engaging introduction....
Digital DC Motor Speed Control With LED Display
Various techniques can be employed to control the speed of a DC motor, including phase-locked-loop principles, digital inputs, or analog inputs. Additionally, the motor's speed can be monitored using LED or LCD displays. The digital DC motor speed controller project...
