These 17HD Stepper motors (also known as NEMA 17 Series) are USED but fully operational prior to removal from their previous purpose (Stage Lighting Moving Head)
Ideal for low cost experimentation (Arduino etc) or possibly parts replacement.
Removed from the original stage moving head equipment because it was based on obsolete technology (metal halide lamps) which "cooked" the top cover (fan failure) and made the equipment unserviceable but perfectly useable stepper motors and various gearing/lens and colour wheels were salvaged - separate advertisements for those components will follow.
RB Stepper Motor
RB is a chinese stepper motor manufacturer (and other associated devices) with an ISO9001 rating for QC
Model: 17HD0005-5
Installed in this equipment around 2005 (although the equipment did not see heavy use)
Identification of the motor model (and lot number) is stamped into the diecast body
Complete with a long flying lead (4 wire) with molex connectors each end for ease of experimentation/fitting.
Basic physical specifications are shown in the photographs.
Technical specifications for this EXACT model I have not been able to find but I have included an extract of technical specifications from RB for similar 17HD series steppers in the hope this provides some sort of guidance about what to expect from these motors. I do not have definitive specifications for the 17HD0005-5
2 Phase
Step angle 1.8 degrees
Measured phase coil DC resistance @ 90 Ohms each
CONDITION:
Clean, bearings "feel" fine
TESTING:
Known to be fully operational prior to removal, tested after removal to confirm the phase coil resistance. This motor was under the control of an STC L6219 PWM controller chip (750mA maximum drive)
Great for robotic motion or mechanical movement experimentation
