quick question about an extruder motor

basically i found a nema 17 motor on amazon for 13 bucks. ill list the details of it and im curious if anyone has inout on it working or not. basically its a spare/test motor incase i suspect a motor failing etc. im just curious to know if this is in the range of yes it should work fine, or possible to work just do all these steps etc.

any imput is appreciated! thank you.

Description
This is high torque Nema 17 stepper motor with 1.8 deg. step angle (200 steps/revolution). Each phase draws 2A, allowing for a holding torque of 45Ncm(63.7oz.in).
It's ideal for the RepRap Prusa, Mendel 90, Rostock and similar 3D printers, as well as CNC and robotics applications.
The motor is supplied with a 1 metre long power cable with a 4-pin Harwin female connector already fitted - ready to plug and print!

100% brand new of "STEPPERONLINE", and ROHS and CE certificated.

Electrical Specification:

* Manufacturer Part Number: 17HS16-2004S
* Motor Type: Bipolar Stepper
* Step Angle: 1.8 deg.
* Holding Torque: 45Ncm(63.7oz.in)
* Rated Current/phase: 2A
* Phase Resistance: 1.1ohms
* Inductance: 2.6mH+/-20%(1KHz)

Physical Specification:

* Frame Size: 42 x 42mm
* Body Length: 40mm
* Shaft Diameter: 5mm
* Shaft Length: 23mm
* D-cut Length: 21mm
* Number of Leads: 4
* Lead Length: 1000mm
* Weight: 310g

Connection:

Black(A+), Green(A-), Red(B+), Blue(B-)

Warning:

* As a stepper motor, it should connect to a constant current or chopper driver. Connecting the motor directly to a power supply will destroy the motor.
* To choose a driver, please make sure the driver's output current not higher than motor rated current, and voltage not higher than 36V.
* Please take care of four wires coils order when you connecting to driver, or it will damage your driver.

Re: quick question about an extruder motor

Bear in mind that stepper motors pretty much never fail.

Re: quick question about an extruder motor

... never fail.

😆

Except you have an filament jam at spool and the extruter is lifting the whole printer 😯
