A step motor, also known as a stepper motor, is a type of electric motor that rotates in small, precise steps. This makes them ideal for applications where precise positioning is required, such as in printers, robots, and CNC machines.
The speed of a step motor is typically measured in steps per second or in revolutions per minute (RPM). The step frequency of a step motor is determined by the number of steps it takes to complete one full rotation, and the speed at which these steps are taken. The number of steps required for one full rotation can range from 200 to 400, depending on the motor design.
In conclusion, the speed of a step motor is determined by several factors, including the number of steps per revolution, the voltage and current supplied to the motor, and the design of the motor. The speed can be controlled by adjusting the frequency of the pulse signals sent to the motor, allowing for precise and accurate movement. Despite the limitations, step motors are a popular choice for applications that require precise positioning and control.
