Step motor NEMA23-05 and driver TB6600 could not drive motor very fast before stalling

[kevin_tee]

Hi,
I have Co-Control Arduino Uno , Joy-IT Motordriver SBC-MD-TB6600, Joy-IT NEMA23-05, and power supply VOLTCRAFT LPS1305.

I follow tutorial from

TB6600 Stepper Motor Driver with Arduino Tutorial (3 Examples)

I want to just spin the step motor very fast, maybe 600-1000 RPM. But I could get it to like ~350 RPM before the motor vibrate and stall.

VOLTCRAFT power supply give 30V during the test.

TB6600 driver is compatible with NEMA23-05 as specified in the spec.

TB6600 Stepper Motor Driver | Joy-IT

NEMA23-05 can reach 1440 RPM according to

NEMA23-05_Datasheet.pdf

I set the switch 1,2,3 of the motordriver to ON, OFF, OFF for microstep4 and pulse/rev 800
and 4,5,6 to ON,ON,OFF for current of 1.5A.

/* Example sketch to control a stepper motor with TB6600 stepper motor driver 
  and Arduino without a library: continuous rotation. 
  More info: https://www.makerguides.com */

// Define stepper motor connections:
#define dirPin 2
#define stepPin 3

void setup() {
  // Declare pins as output:
  pinMode(stepPin, OUTPUT);
  pinMode(dirPin, OUTPUT);

  // Set the spinning direction CW/CCW:
  digitalWrite(dirPin, HIGH);
}
int step_delay = 120;

void loop() {
  // These four lines result in 1 step:
  digitalWrite(stepPin, HIGH);
  delayMicroseconds(step_delay);
  digitalWrite(stepPin, LOW);
  delayMicroseconds(step_delay);
}

step_delay = 120 is the smallest step I can use before stalling at 110 with a lot vibration.

Thank for the help.

To achieve higher speed You need use acceleration. Chech the stepper "Run in" parameters. That's the maximum speed running the stepper like You do.

NEMA23-05 can reach 1440 RPM according to

According to datasheet you need 50V to reach 1440 RPM and will only get very little torque. And as @Railroader pointed out you need acceleration to reach such high speed. A stepper cannot reach such speeds directly from standstill.

Thanks, I just figured that out. I will need power supply with higher voltage and acceleration control.
