1, what is the stepper driver half-current hold function? Half-current drive is a commonly used control method in stepper motor control. The realization of half-current drive requires the stepper driver to have the ability to select half-current drive....
Multiple devices with the same I2C address? Don't like bit-banging? No money for extra I2C multiplexer? Spare IO ports ? ==> Continue reading ! This was a short proof of concept to use the IO_MUX capability of the ESP32 to change...
What is TMC5160 The TMC5160/TMC5160A is a high-power stepper motor controller and driver IC with serial communication interfaces. It offers a flexible ramp generator for precise target positioning and features the industry's most advanced...
Hi, I'm Rue Mohr, you might know me from such places as the internet, the information superhighway, or the world wide web. Today I'd like to tell you about an adventure in optimization of a 7 segment decoder. (7 segment display with the highly...
This year for SuperCon, I took the awesome vectorscope badge that the team had created and got it to play some short video clips from the Raspberry Pi Pico's 2MB of flash space on it's 1.8" round LCD screen with a GC9A01 driver chip.This required trying...
Here is a quick troubleshooting guide on how to solve the problem of a stepper motor or BLDC motor not spinning after being connected to a drive. First, we recommend that you perform the following troubleshooting steps: 1. Check all wiring carefully....
Compared with ordinary traditional motors, brushless DC motors have the advantages of high power density, high efficiency, and long life. Brushless DC motors have a simple structure and few components, so they are easy to maintain and have a long service...
Servo motors and ordinary motors are electromagnetic devices that convert or transmit electrical energy. They have the same function. However, there are certain differences in their structures, accessories, prices, applications, etc. Generally speaking,...
How to adjust the speed of brushless motor? It is different from the speed regulation of stepper motors (the principle of speed regulation is to rotate a step angle every time a signal is received, so the speed regulation method of stepper motors is...
Programming 2764 EPROM with a Mega2560, SD card reader and 5-12V Buck converter If you have ever wondered what it would be like to have a real retro -computer-nerd experience, then maybe programming EPROMs will fit the bill for you. Since the late 60's...
Stepper drivers are very important for the normal operation of stepper motors and brushless DC motors, so in order to make the motor work better, we need to understand the stepper driver. Today, let us first take a look at the signal output ports...
Cause of motor heatingFor any motor icluding sevomotor spindle motor, brushless dc motor,etc,It is normal to heat up during operation, and the same is true for stepper motors.The interior of the stepper motor is composed of an iron core and a winding...
When using T6 servo motor, if jitter occurs, you can eliminate it through the following methods.When the brake is open, the mechanical installation is balanced, the coupling does not shift, the gear meshes well, the encoder wiring is correct, and there...
1. Causes of motor heating For any stepper motor, it is normal to generate heat during operation, and the same is true for stepper motors. The inside of the stepper motor is composed of an iron core and a winding coil. The resistance of the...
1. What are phase inductance and phase resistance? Phase resistance refers to the resistance in each phase coil of a stepper motor. Inside the stepper motor, there are two or more phase coils. Each coil has a phase resistance, and its size depends on...
