Stepper motors are awesome for their precise movements, but sometimes you just need them to slow down.
Here’s a quick look at some of the methods you can use to limit the top speed of your stepper motor:

PWM doesn’t give the motor full power all the time. Instead, it turns the power on and off very fast, making pulses. The longer the pulse stays on, the faster the motor spins. It’s like making a light brighter or dimmer by flicking the switch fast – the longer it’s on, the brighter it gets.
Current limiting in stepper motors is like controlling the flow of fuel to a car’s engine. In a car, less fuel means the engine runs slower. In a stepper motor, the current is the fuel. When you limit the current, the motor slows down.
Ways to Limit Current:
Current limiting is a good way to control your stepper motor’s speed. It’s useful when you need the motor to move at a certain speed, like in 3D printers or CNC machines. By controlling the current, you control how fast or slow the motor turns. This method is simple but very effective for precise speed control in different applications.
Microstepping in a stepper motor is like adding small steps between the big steps. It gives you more control over how the motor moves and how fast it goes.
How Microstepping Works:
Benefits of Microstepping:
Microstepping is useful for jobs that need careful and smooth movements. This includes things like robots, 3D printers, and machines that cut or shape materials (CNC machines). It helps these devices work better and more accurately.
