Can anyone answer me these questions 1. Is this is a DC or AC

>>1141251
1. You can find out yourself.
2. Probably, but take caution.
3. Got me. Have a bump.

>>1141251
a quick google indicates it's ac, specs as pic, don't run over 60 mins because overheat

>12V
>117A
no

>compounds
angry pixies

>how to test run
you need a power supply that feeds the correct pixies

>electric bike
no

A 4 kw ebike... wow

>>1141251
Shit man 28volts 117 amps.
Id guess thats off of a forklift or other electrick MHE. If so its ac and the plastic connector is feedback from an encoder so the motor controller knows which winding it needs to feed. You will have major problems trying to use this

>>1141251
That motor is more suited to a small electric car. A human, pedaling hard, produces around 0.2kW. 4kW on a bicycle will either snap the chain or make you do a backflip.

Also, by the looks of it you'll need a 3-phase VFD to run it.

They forklift motors - prob get enough selling that to buy a noo e-bike, just need to wait on a willing buyer appearing. And wait. Also, if you have trouble picking it up (weight)?, its prob not best suited to a bike project - car/cart, sure, be better if you also had the controller tho, obv.

this is not a 3 phase motor, its a dc motor.

the only difference between most of the people replying this thread and the op is at least the op knows he doesnt know what is going on

>>1141360

Spec sheet says its a dc motor, but looking at the picture there are no brushes.

either way not appropriate for this project

>>1141360
>its a dc motor.
28V
90Hz

>>1141389
Nope 100 percent ac motor it's a drive motor black on top is break three hole for three leads for the traction amp and so on

>>1141271
I'd like to see that. Would be even better than that guy on a starter-motor go-cart.

>>1141475
>starter-motor go-cart
that doesnt sound like it would last long

>>1141486
But you only have to accelerate for a second, so the duty cycle is still low enough!

>>1141251
Tag says 90hz
Just going to take a guess it's A/C

>>1141251
Its a fork lift motor. juli.cz is their website. 28V AC 90hz means you need a proper motor driver/controller. if you dont have that, the motor is worthless to you.

that thing looks fun as fuck

the acceleration has back snapping capability

>>1141251
As has been said it is AC.

Yes you can power it from 12V batteries.

You need:
A three phase IGBT motor driver.
A microcontroller, just about any will do.
6 NMOS logic level mosfets.
Some miscellaneous resistors.
A good bit of 2/0 wire.
2/0 solder terminals.
A degree in electrical engineering.

or

24V three phase AC motor driver

OP is a faggot

>>1142157
in all fairness, wtf info OP s'posed to gather from that Czech waste of bandwith? Assumed they just couldn't into English, tried it in 3 languages - it literally has no information whatsoever in fucking any of them. No wonder the Russians left.
