Hello, Locking the sleeve with Loctite is a good idea. In that case I can choose a lighter transition fit (H7/k6). With 356H7/k6 there is a max. interference of 0.040mm and max. clearance of 0.053. In order have the sleeve's ID 340 within H7-tolerance (+0.057/0.000) after installation, I think...

Hello JNieman, Post-assembly machining (line-boring) is what I like to avoid. We first like to line-bore the hub inner diameter 356H7 and then insert the sleeves with H7m6. This may make the inner diameter of the sleeve to shrink. I thought it shrinks the same as the interference of the H7m6...

Hello, I am having difficulties selecting the correct tolerances for a sleeve (stationary bush) which will be fitted (with a H7/m6 transition fit). Attached the situation sketch. Some fixed figures: Hub outer diameter: 700 mm Hub inner diameter: 356 H7 Sleeve outer diameter: 356 m6 Bush outer...

Hi Carlos, Thanks a lot! What would be the effect when I wire the E-motor as per manufacturer diagram (compared to the original diagram)?

Hi Carlos, You're right, the replacement motor comes from the Brazillian market. So if I understand you right, if I connect the lead U4-W4 as per original drawing, there is no chance that this harms the motor (e.g. starting CW in star, en then turning CCW in delta)? It may only affect the...

It only allowed me to upload one file with the post. Hereby the other document (the original diagram).http://files.engineering.com/getfile.aspx?folder=a183971c-a11c-4d6d-b61a-181c4cc9bf41&file=AC_fan_motor_origineel.pdf

Dear all, I hope you can help me out with following question related to the wiring of a 3-phase electrical motor with a Y/Δ starter. Originally I have a ABB motor (M2AA type) which is when switched in delta: V2 switched to U1 (via phase L1) W2 switched to V1 (via phase L2) U2 switched to W1...

Thanks guys, for all the useful info! It's clear to me. In general rewinding for a non-defective E-motor is not advisable (since costs will be increased).

Hello everyone, I was wondering if anybody knows a leaflet/book/document wherein a number of standardized overhaul-works are specified. I can imagine that a lot of overhaul works (like for E-motors, hydraulic pumps, propeller/rudder arrangements, piping etc etc) described/specified in a...

Hello everyone. I was wondering if somebody could advise me what the 'standard' scope of work is for an overhaul of an 3-phase 400V E-motor (like type 225M). Renewal of bearings and cleaning of the coils are obvious; but should works like 'rewinding of stator/rotor coils' also be advisable? And...
