Nema 23 Bipolar Stepper Motor 2.0A 1.2Nm Round Shaft

Description

Stepper motors convert electric pulses into mechanical movement in stepped increments. The rotation has a direct relationship with the applied pulses. The sequence of the pulses dictates the direction of the motor shaft rotation, the frequency of the pulses dictates the speed of the shaft rotation, and the number of input pulses applied is directly related to the distance of rotation.

There are many advantages to using stepper motors. Among others, they have full torque at standstill, offer excellent response to starting and stopping, and provide open loop control. This stepper motor also have step accuracies of 5% of the step, which provides precise positioning and repeatability of movement. These features make it possible to achieve very slow speed synchronous rotation with a load directly coupled to the shaft—ideal for positioning applications.

This is two-phase stepper motors, which are the most common type of stepper motors. They operate by alternating the magnetic field the windings produce by changing the direction of the current in the windings. Thus, attracting or repelling the magnetic poles of the rotor causes it to rotate in step with the incoming pulses. Two-phase steppers come in unipolar and bipolar versions.

This 23HS6620 stepper motor can be connected in bipolar or unipolar configuration. For unipolar configuration you must use all 6 wires, while for bipolar configuration you use only 4 wires. Depending on which 4 wires you use, you can obtain two modes of operation; choose one according to your needs:

• To achieve a higher holding torque (1.26N.m) but at a lower speed: Black:A+, Green:A -, Red:B +, Blue:B-, Yellow and White do not need to be connected.
• To achieve a lower holding torque (0.90N.m) but a higher speed: Black: A +; Yellow: A-; Red: B +; White: B-, Green and Blue do not need to be connected.

One of the major benefits of a bipolar stepper motor is that they provide more torque at low speeds when compared to unipolar stepper motors. This means that bipolar stepper motors are best suited for applications that require high torque at low speeds.

Bipolar stepper motors require special drive circuit, called an H bridge. This 23HS6620 stepper motor is compatible with TB6600 driver and DM542 driver. 24 V Switching Power supply or 36 V Switching Power supply is recommended.
