Stepper motor acceleration calculator


If you want to accelerate faster, you give the car more gas. Step motors are similar, following Newton’s famous law F=ma. In rotational terms, Newton’s law is expressed as Torque (T) is proportional to rotor and load inertia (J) and angular acceleration (A). If you have a heavier load or want to accelerate faster, you need more torque..

Stepper motors divide each full rotation into a number of equally sized steps. Also known as step or stepping motors, these 2-phase brushless DC motors offer quick, precise load positioning and exceptional holding torque at any of these incremental steps. Each step represents 1.8°, or 200 steps per revolution..

If I adjust the speed, after every time I take a step, the acceleration is not linear. I tried to calculate the braking distance with: pulses = V V / 2. Which I derived from basic movement and travel formula. S (t) = S0 + V0 * t - 0.5 A*t^2. I take 1 for A and 1 for T. Every time I inc/dec the speed with 1. So I get S (1) = V^2 - 0.5 * V^2 = 0. Web.

For a stepper motor, we would need to meet or exceed the following requirements. Load Inertia = 5.56 × 10−4 [kg·m2] Total Torque = 0.85 [N·m]* Maximum Speed = 1200[r/min] For a servo motor, we would need to meet or exceed the following requirements. Load Inertia = 5.56 × 10−4 [kg·m2] Total Torque = 0.85 [N·m]* RMS Torque = 0.24[N·m].

Select a motor type from AC Motors, Brushless DC Motors or Stepping Motors based on the required specifications. Make a final determination of the motor after confirming that the specifications of the selected motor/gearhead satisfy all of the requirements (mechanical strength, acceleration time, acceleration torque etc.). Determine the drive.

To estimate the stepper motor's speed, engineers would first have to calculate the motor's number of steps in one revolution (360°) . This can be obtained below: By introducing this value into the stepper motor speed equation, engineers would obtain 6 rpm (or 0.1 revolutions per second).

Key-in all commonly required parameter values like weight, friction, acceleration time that influence the motor torque or power required in order to achieve the desired motion system.

Your motors are relatively high voltage and high inductance so it will require a high voltage to drive them fast. If your drives are not currently on a power supply close to their rated voltage consider getting a higher voltage supply.

Web. Another consideration when accelerating a stepper motor is current supply. Too little current and too high an acceleration means that the motor won't have enough power to accelerate both itself and the load it is driving. It may stall if this condition persists. On the other hand, every system has an upper limit of maximum allowable current supply.

The speed of the stepper motor is determined by the PWM frequency output to the drive, and a timer (TIM2_CH1) using the MCU (TIM2_CH1) is used to output a pulse of the duty ratio D = 50%. The clock frequency of the timer is 72 MHz, 8 MHz after dividing, so the lowest frequency of the output PWM is approximately 120 Hz..
