    Range Rover steering column motors

    So this is the wiring schematic for a RR Vogue steering column - in itself nothing spectacular, just two motors making it go up/down and in/out. Except, looks to me that each motor has a PL and effectively a single SL coming from off a digital controller (it links in with memorised seat...

    Learning electrical motors

    Hi, I’m Not getting enough torque on startup to turn pump. Turns pump successfully maybe 1 in 6 times on startup and then fine at full speed. Currently connected in star as per plate, 400V. Ran from a three phase inverter. Should this be wired delta? Still very much learning.

    Wiring Multiple VFDs off Dryer Plug for Multiple 3-phase Motors

    Posted this to the DIY section since I'm not a business or employee in this matter but it feels more appropriate (and might actually get responses) here. Hi all, I'm new here but have posted on Hobby-machinist and Practicalmachinist forums. I want to wire up an electrical box for a milling...

    Which contactor utilization category for electronically controlled motors: AC-1, AC-7a, AC-7b ...?

    Many devices with motors in them now have electronic controls, e.g. "inverter" aircons/fridges. Many include include soft-start and power-factor correction, etc. Should these devices still be considered as inductive/motor loads (AC7b) or a different utilization category?

    About Stepper Motors

    Actually there is another forum discussion until reaching this cct here. It was an entire evolution of it. This cct is working ok but in certain parameters. It is limited to power and heat over the Tr's. Is working fine in the 5V range for 2 of my stepper motors that I tested with it. But if Im...

    Can multiple motors share 1 mcb.

    Hi, I am installing 24 No 2.2Kw 3Ph motors that will drive cooling fans. The plant room for the install is not what you would call spacious so trying to keep everything as tight as possible within reason. The motors are all controlled through an automated system which feeds back to an...

    Winding resistance tolerances in three phase motors

    Hi guys, Is there a standard tolerance percentage that should be followed when checking the winding resistance of each coil on a three phase electrical motor? The general rule of thumb I followed when measuring winding resistance was that each phase winding had to be identical or close to...

    motor used simultaneously

    Hi there, i will be on a job soon that requires two motors to control a belt that delivers grain to the opposite end of a grain shed these motors need to run simultaneously. this is due to the length of the shed which id say is 72 meters one motor at the start of the belt and another 72 meters...

    Best way to step up voltage for electric motors

    We've been tasked to run power to some electric motors on some pumps and the building is currently 120/208vac 3ph. The motors are 230/460vac 3ph. Instead of getting new motors that run on 208vac, they're asking if we can get a transformer to step up the voltage from 208vac 3ph to 240vac 3ph. The...

    Can a 3 phase motor that is running on single phase have 2 directions?

    I am needing to know if this wiring diagram is showing a few things: 1: Does this show a 3 phase to single phase conversion? 2: Does this show that the motor can turn in 2 directions with the same internal wiring if you toggle the SPDT switch?

    Ebay motors

    As a winter project I'm building an electric trike. I'm thinking of using a go-kart motor to power it on the rear axle. An ebike front wheel conversion 26" 250W was not successful. Some Ebay motors seem to make fantastic power claims of 1800W or even 3000W on what looks like a very small unit of...

    UK Large single phase motors in the UK

    Why is it that I could easily find a 10HP 220V single-phase motor for sale in the USA but in the UK I nobody has anything larger than 5HP?

    Capacitors in motors

    Hi All, Had a farmer I’ve done some install work for call yesterday saying overload was tripping on his vac pump and could I get some new capacitors ( thought it would be simple enough as changing like for like). When I got there to have a look he said the guy who looks after parlour (...
