How do you size a stepper motor?

How do you calculate stepper motor?

For example, for Trinamic Motion Control GmbH, QSH4218-35-10-027, its step angle is 1.8⁰. So the number of steps per revolution = 360 / 1.8 = 200. This is a fixed relationship – all 1.8⁰ step angle stepper motors will have 200 individual steps.

How do you size a motor?

Divide the motor speed by the required speed and round down to get a starting gear ratio. Then divide the required torque by the gear ratio to find the newly required torque. This will help you narrow the choices down to a few select motors.

What is a 42 stepper motor?

NEMA 42 stepper motor is the largest step motor of the stepper motor family. This is known to be the finest type of stepping motor. … The nema42 stepper motor is mainly used in the applications where precise and efficient motion control is required whether the motion is linear or rotational.

What is NEMA 17 stepper motor?

NEMA 17 stepper motors are those that have a 1.8 degree step angle (200 steps/revolution) with a 1.7 x 1.7 inch faceplate. NEMA 17 steppers typically have more torque than smaller variants, such as NEMA 14 and have a recommended driving voltage of 12-24V. These steppers are also RoHS compliant.

What is RPM of stepper motor?

Stepper motors are high pole count DC motors that are driven with a DC pulse train. Mechanical designers frequently create systems designed to use stepper motors at relatively high rpm based on the maximum motor speed rating (often 3000 rpm) and the motor torque vs. speed curves.

How many watts does a stepper motor use?

x. If you are actually using 2 phase steppers with a maximum of 4.5 A (the capability of the controller), then you might expect 4.5^2 * 0.6 = 12 W per phase. If you use x2 (400 step, which is half step) micro-stepping then with both phases on you’d get maximum dissipation of about 24 W.

What is the difference between a servo motor and a stepper motor?

The main difference between these motors comes from the overall pole count. Stepper motors have a high pole count, usually between 50 and 100. Servo motors have a low pole count – between 4 and 12. … Servo motors require an encoder to adjust pulses for position control.

How do I choose the right motor?

Consider an application’s purpose and which current it uses to select the appropriate type of motor. An application’s specifications such as voltage, current, torque, and velocity will determine which motor is most appropriate so be sure to pay attention to its requirements.
