Motors

[Zero the hero]

Hey people, I've planned to build a propeller clock, but I need a motor...
I wanted to use a couple of motors taken from old VCRs, expecially the motor for the heads and the one for the load mechanism.
Unforunately, the don't work with simple DC current: they have 4 wires and not 2 ( as I expected from a motor).
Anyone knows how to drive them?
Any link?
Thnx
Zero.

I got a slew of motors here from VCR's and other scav items, and 9v fires em right up...

If they are brushless motors they require special controller circuits.

they're dc brushless as mentioned B4.

google 4 "stepper"   "schematic"   "vcr"

a DCBL motor need some kind of feedback 2 indicate
where the rotor is.  A stepper does not.
they are both similiar in operation.

google 4 "brushless motor"  etc.

there R LOTS! of pages on stepper motors and such.

actually any motor that can operate with a speed control
will work for the propeller clock.
The trick is to syncronize the rotational speed with the display speed.
