Each ON/OFF cycle is counted as one pulse. A command with one pulse causes the motor output shaft to turn by one step.
The signal levels corresponding to voltage ON and OFF conditions are referred to as "H" and "L," respectively.
What is a Pulse Signal?
• The length of Rotation is Proportional to the Number of Pulses
The length of rotation of the linear stepping motor is proportional to the number of pulse signal (pulse number) given to the driver.
The relationship of the stepper motor's rotation (rotation angle of the motor output shaft) and pulse number is expressed as follows: The length of Rotation is Proportional to the Number of Pulses
The length of Rotation is Proportional to the Number of Pulses
• The Speed is Proportional to the Pulse Frequency
The speed of the stepper motor is proportional to the frequency of pulse signals given to the driver.
The relationship of the pulse frequency [Hz] and motor speed [r/min] is expressed as follows: The Speed is Proportional to the Pulse Frequency
The Speed is Proportional to the Pulse Frequency
• Generating High Torque with a Compact Size
Stepper motors generate high torque with a compact size.
These features give them excellent acceleration and response, which in turn makes these motors well-suited for torque-demanding applications where the motor must be started and stopped frequently.
To meet the need for greater torque at low speed, MOONS' also has geared motors option.
• Frequent Starting/Stopping is Possible
• Speed VS Torque Characteristics comparetion between servo and stepper with same motor size.
Frequent Starting/Stopping is Possible Speed VS Torque Characteristics comparetion between servo and stepper with same motor size.
• The Motor Holds Itself at a Stopped Position
Stepper motor closed loop has full torque at stand-still as long as the windings are energized. This means that the motor can be held at a stopped position without using a mechanical brake. The Motor Holds Itself at a Stopped Position
• Motor with Electromagnetic Brake
Once the power is cut off, the self-holding torque of the motor is lost and the motor can no longer be held at the stopped position in vertical operations or when an external force is applied. In lift and similar applications, an electromagnetic brake type motor is required.
