Heidelberg Windmill Electrical Specs

Hello. I need to get this information to my electrician who is not familiar with printing presses. Aside from what is on the motor, can anyone give me any information?

Thank you.

Really the only electrical specs of the T-Platen would be those of the motor itself. Motor turns the pulley, turns the flywheel… powers the whole press. All of this through an amazing system of cams, gears, etc. No electrical parts aside from the motor.

Many Windmill motors are 220/240v 3-phase, but not all. If your electrician can wire the motor to power and a switch… you should be in good shape.

Good luck!

I hooked my presses up with liquid-tight plastic conduit to prevent stray oil and solvent from affecting the wires. They’re supposed to be “oil-resistant” but I’d prefer to be safe than sorry.

The drawback to this is that the conduit does not function as a ground. Since the motor was not supplied with a ground wire, I screwed a grounding lug to the motor body (inside the wiring box on the motor) to connect to the ground at the motor starter box.

My motor is 1-phase, and I am unfamiliar with 3-phase wiring.

Our windmills run on 3-phase power, on one and a half horse power motors. They are hardwired for the appropriate power, but in our old space, which only had 110, we needed phase converters. As said above, you need to accomodate the motor. If the motor runs on 110, then you need 110, if it is specified for more, you need to adjust the power for that , by either a new motor, or a phase converter. Your electrician should be able to know what to do by looking at the motor specs on your press.

My press is set up for 220 volt 3 phase and I have it running with a static phase convertor. The only problem that can occur is if I want to start the motor while the press is turned up to a high rate of speed—that create too much a starting load and the convertor makes very unhappy sounds (shut if off quickly at this point)

If you have a rotary phase convertor, you should not have this problem.

If you are not comfortable with wiring, your electrician should be able to work out a solution, three phase should not be a reason to pass on a press.

I am in the process of buying a redball, but I need to rewire my shop to handle the extra load. Can someone tell me the amp draw from the standard 1.5hp motor?



I think it would be far cheaper to just buy a 220 single phase motor that turns at the right speed and call it a day. Trying to replicate 3 phase power for a 1.5 hp motor is a waste of time. And, I believe, more costly than just getting a “regular” motor.

I recently purchased a Heidelberg Windmill that came with a three phase motor. I purchased a single phase motor so I could run it on residential power and was told that I would need a motor starter to go with the motor. I I have everything hooked up per the diagram that was given to me, but there’s a problem. When I push the start button, the motor stater toggles and the motor turns the flywheel, but as soon as I release the start button, the motor stops. I’m sure something must be wired wrong, but I think I’ve tried all combinations and still it doesn’t work properly. Can anyone help?

To Goomis, I think you should maybe check whether any other electricians in your area might be able to help you. I got my electrician who had not trouble putting in a 3-phase powerpoint and attaching a new lead from my powerbox for my Heidelberg Windmill. I am very new and couldn’t give him much knowledge either.
