What is the control technology for the acceleration and deceleration process of stepper motors?

Stepper motor acceleration and deceleration process control technology is a technology used to control the speed and acceleration of stepper motors. This technology is usually applied in situations that require precise control of motor speed and acceleration, such as robots, automation equipment, industrial control systems, etc.

During the acceleration and deceleration process of the stepper motor, the controller will calculate the number of steps and acceleration that the motor needs to rotate based on the required motion trajectory and speed curve, and send corresponding pulse signals to the motor through the driver.

During the acceleration phase, the controller will gradually increase the frequency and quantity of pulse signals, causing the motor to gradually accelerate to the desired speed.

During the deceleration phase, the controller will gradually reduce the frequency and quantity of pulse signals, causing the motor to gradually slow down until it stops.

During the control process, the controller will also adjust the frequency and quantity of pulse signals based on feedback signals to ensure that the motor can move accurately according to the required trajectory and speed curve.

In summary, stepper motor acceleration and deceleration process control technology is a technology used for precise control of stepper motor speed and acceleration, widely used in fields such as robotics, automation equipment, industrial control systems, etc.

Stepper motor acceleration and deceleration process control technology is a specialized control technology used to manage the start, stop, and speed changes of stepper motors.
This technology is mainly achieved by controlling the pulse frequency to prevent the stepper motor from starting up normally due to too fast a frequency, and to avoid the motor losing step or overshoot caused by too large a change in the control pulse frequency.
In the acceleration and deceleration control of stepper motors, the trapezoidal acceleration and deceleration control method is usually used. This method forms a trapezoidal curve with time as the x-axis and velocity as the y-axis.
At startup, the motor gradually accelerates from low speed to the target speed.
When stopped, the motor gradually slows down from high speed to zero speed. This acceleration and deceleration control method can make the stepper motor start and stop more smoothly, avoiding impact and vibration caused by speed changes. At the same time, it can effectively prevent the phenomenon of step loss and overshoot of the stepper motor, improve the control accuracy and stability of the motor.
