HobbyStar 3665 4-pole brushless motor provides increased torque when compared to a shorter can while still providing top-end power. Versatile waterproof design allows you to drive in extreme conditions and motor leads come with pre-installed 4.0mm gold-plated bullet plugs for easy, no-soldering connection.

Features:

  • 4-pole motor with 12-slot high-torque design
  • High-purity copper windings maximize efficiency
  • High-RPM ABEC5 oversized bearings
  • Precision balanced rotor for smooth operation and maximum RPM
  • Super-thin (0.2mm) stator laminations 

Voltage recommendations in the table below are guidelines for the voltage you can safely run.  It is still critical that the user monitor motor temps and adjust gearing if necessary, any motor can overheat to the point of destruction if over-geared even when running at or below the rated voltage.

      Might Need to Turn Off Security Measures in Order to Download
      I'm a 1st grade teacher and use my ET-2800 religiously. We own 4 of them, between home, my husband's and my classroom, and one for sublimation. I've printed over 15,000 copies on my school printer in the last few years and had no idea about the ink pad replacement until the error message popped up and wouldn't work anymore. I originally purchased a different set and couldn't get it to work. I was in panic mode so I ordered this set, which also originally didn't work. After really paying attention to the alerts that were popping up, I finally had to Google how to turn off my McAfee and Windows Security programs. They were blocking it from running. Once I did that, it was able to install and it is back up and running again. It did make me very nervous to turn them off but as soon as I got it installed, I turned them right back on and ran scans. So far I haven't had any issues in the last few days. The installation is extremely easy, it came with gloves, a screw driver, etc. Mine wasn't messy, so I didn't need the gloves or anything. It's also a 3-pack, so I left myself reminders for next time on how turn off the security. If you are having installation problems, turn off all of your malware security and that will probably help. Just make sure you turn it back on and run scans, the whole process with all of these websites seems shady and scary at first, but this one appears to be legit. I did read that Windows 10 and 11 tend to block sites that are deemed safe.

      Recommend without hesitation
      I don't typically write reviews but wanted to let people searching for a solution to this Epson inkpad problem that they should not hesitate to order this product. I got it yesterday and had my printer back up and printing in 10 minutes--Epson wanted me to buy a new printer or hire a certified repairman! btw, I did not see what others referred to as a sketchy website for downloading the software and I did not need to disable my antivirus software to complete this task.
