STEPPER MOTOR 5VDC UNIPOLAR

STEPPER MOTOR 5VDC UNIPOLAR

Description

• This is a great first stepper motor, good for small projects and experimenting with steppers.
• This uni-polar motor has a built in mounting plate with two mounting holes.
• There are only 32 step (11.25 degree) per revolution, and inside is a 1/16 reduction gear set.
• (Actually its 1/16.032 but for most purposes 1/16 is a good enough approximation) What this means is that there are really 32*16.032 steps per revolution = 513 steps!
• The shaft is flattened so its easy to attach stuff to it with a set-screw.
• A perfect first stepper motor and works well with the Motor Shield for Arduino.
• The gearing has a few side effects which are important to note.
• First, you can turn the stepper by hand but not as smoothly as an un-geared stepper.
• It also means you shouldn’t use interleaved or micro-stepping to control or it will take forever to turn.
• Instead use single or double stepping.
• The torque is fairly high but its slower than un-geared steppers – we maxed out at about 80 RPM when powering with 12VDC and about 50 RPM on 9VDC.
