The Purchaser will supply the Auctioneers proof of adequate insurance before the removal of item(s) that require dismantling, rigging or hot cutting. The Purchaser, if asking the Auctioneers to assist in the removal of any item(s) will indemnify and hold the Auctioneers and/or their staff harmless from any resulting loss or damage to the item(s) being removed. When you press the jog button, the electromagnet releases the brake allowing the spindle to turn.All costs and the responsibility of removal will be borne by the Purchaser.
My european milling machine has a electromagnetic brake on the main drive motor. I couldnt find a transformer for the brake, so I was assuming that is what it was missing. I am looking a the timer may no have worked to switch contractor to change mode from starting to running. I am trying to figure out that if the motor run okay why the motor contact would weld together. So the motor is not dual speed, it is just a change in configuration wiring to limited current draw while stating. There is a tag that appears to say 50V near the missing burnt out part, maybe missing transformer Maybe tag misleading. You could probably measure resistance across the control circuits and determine their voltage inputs. So you might try to break it out into systems: brake, control, Load (ie motor) and then try and see what is missing. I have also experienced reduced voltage control circuits AC 24 volts is common. If it was 2 speed, you would think it would have the pole numbers on the plate like 84 for example, plus would have the speed, that speed is fixed at 1740 by the looks of it. Is my currents values going to change or stay the same Somethin I will do tomorror is disconnect the motor leads and measure single windings resistance and megger 500 volts, is that a good idea. Can I do it in the first speed measure curents then rewire for the high speed. I know to read the name plate but when it come to test and energize the motor, not sure. I work with pump and fans but they have always been 3 phase motors. It would give you a control diagram, but all the component parts will likely be described in Japaneze and not easily found, but can be replaced with comparable available parts. If you are not familiar with industrial electrical controls then hire an electrician with industrial machinery experience and save yourself a lot of grief. Mazak Lathe Mate Trial Electrical Controls It is not a two speed motor is it That model was copied in China by JFMT (Jinan First Machine Tool Group) and is still produced, for example - NEW Jinan JFMT 460 18 lathe. The switches are most likely 110v, which operate the main relays to give you forwardreverse.
