Stepper NEMA 17 Bipolar Motor 42 x 42 x 34 mm

Stepper NEMA 17 Bipolar Motor 42 x 42 x 34 mm - This bipolar stepper motor uses 4 wires to control its positioning and/or speed control. It has a low noise and low heat. It can run smoothly with a good acceleration performance. This stepper motor adheres to NEMA 17 size.

We also have the 42 x 42 x 48 mm version.

Frequently Asked Questions About NEMA 17 Stepper Motor Dimensions

Q1: What use does the NEMA 17 motor?

The NEMA 17 hybrid stepping motor has 200 steps per revolution and a 1.8° step angle. Holding torque of 3.2 kg-cm is possible with each phase drawing 1.2 A at 4 V. Printers, CNC equipment, and laser cutters commonly employ NEMA 17 stepper motors. There are two split windings and six wires connected to this motor. Red, White, and Blue wires make up the second winding, whereas Black, Yellow, and Green wires make up the first winding.

Hard drives, linear actuators, and CNC machines all frequently employ NEMA17 stepper motors. The motor has six lead wires and is rated for a 12-volt system. Lower voltages can be used, but the torque will decrease. These motors have a step angle of 1.8 degrees, which means that each of the 200 steps in a revolution will cover a 1.8°, resulting in a great degree of control. Due to their 12V operation, these motors have a high torque capacity. So this motor is a good option if you're searching for a small, user-friendly stepper motor with a lot of torque.

Q2: How to Control the Speed of a stepper Motor?

The Arduino Stepper Library is used to control the rotor velocity of a stepper motor using a potentiometer (or other sensors) on analogue input 0. Digital pins 8, 9, and 10 and pin 11 are used to control the stepper for either unipolar or bipolar motors. Additionally, Dual-phase full-step excitation involves operating the stepper motor with two phases powered on simultaneously. This mode has few resonance issues and offers good acceleration and torque performance.

Q3: What benefits can stepper motors offer?

A stepper motor won't be useful in every application, but in the right circumstances, it can be perfect. The torque of stepper motors is maximal at rest, and the motor's rotation angle is dependent on the input pulse. In general, stepper motors provide precise positioning, great speed control, and repeatable movement.

Since the motor has no contact brushes, stepper motors are also very dependable. This increases the motor's operational lifespan and minimizes mechanical failure. Because the rotational speed is related to the frequency of the pulse inputs, these motors can be used in a variety of settings.
