[QUOTE="Marvo, post: 483763, member: 20838"] The motor is capable of running for very short periods wired in star with a neutral or wired in delta with no neutral with a maximum run current of either 9.1 Amps or 5.49 Amps respectively. Which way it's wired would depend on the the overall design of the car ramp. Your whole post is making me skittish......Retrofitting a VFD or fundamentally altering the design of the machine in any way could introduce issues with other aspects of the overall operation of the machine such as any motor braking systems or any ancilliary systems such as safety locking solenoids and control systems such as E-Stop etc. The entire machine would need recertifying as being safe for use after any modifications to its design and, I'm not UK based but as far as I know in the UK, failing to do so would make you personally liable for any subsequent safety event such as injury or death. The voltages stated are all nominal, it's not unusual to for motors that are stated as being 380v to run on a supply that's actually 400v and vice versa, motors rated at 400v run on a 380v supply. This is especiall true for S2 duty motors but you can check the motor manufacturers website for confirmation. If you're supplying the machine from a generator you shouldn't be modifying any motor wiring, you'd just connect the generator supply into the power terminations in the control panel of the car ramp, they should be labeled as L1, L2, L3, N and Earth.
