NEMA 17 hybrid stepper motor 17HS4401 with 1.8 degree step angle and 1.5 A rated current

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.

The 17HS4401 is a NEMA 17 hybrid stepper motor with two phases and a 1.8 degree step angle. The motor is designed for applications requiring precise positioning and controlled rotation, such as CNC machines, 3D printers, robotics, automation and various electronics and DIY projects.

The motor is a bipolar hybrid stepper motor with two separate windings and is suitable for use with a current regulated stepper motor driver. A driver can, for example, be supplied with 12 V or 24 V while regulating the current through the motor windings. A higher supply voltage to the driver can provide better performance at higher speeds because the current can build up faster in the windings.

The motor has a rated voltage of 3.3 V DC and a rated current of 1.5 A per phase. The rated voltage should not be confused with the drivers supply voltage. The rated voltage describes the approximate voltage across the motor winding at rated current and is related to the winding resistance. The motor should normally not be connected directly to a power supply but used together with a suitable current regulated stepper motor driver.

The 1.8 degree step angle means that the motor has 200 full steps per revolution. With microstepping, each step can be divided into several smaller steps for smoother operation and higher resolution. Microstepping does not automatically provide a corresponding increase in mechanical positioning accuracy.

Motor length is also an important characteristic of stepper motors. A longer motor from the same series is normally designed to provide higher holding torque and running torque, but motor length alone is not an exact measure of motor strength. When comparing different models, the holding torque specified by the manufacturer should be used as the primary value.

The specified phase resistance of 2.22 ohms is used together with the rated current to describe the motors electrical characteristics. At 1.5 A, the resistance gives a resistive voltage of approximately 3.33 V across one phase, which closely matches the specified rated voltage of 3.3 V. The resistive power is approximately 5 W per active phase.
