Unknown Motor

07/28/2019 4:50 AM

I recently acquired this electric motor. It appears to be 220volt 50hz. Can anyone identify it's use.

Box on top of motor.

Contactors in box.

Switch gear on end of motor.It has a cam that operates two contacts and has what looks like timing marks. see pointer on shaft.

In the early days of electrification, there were lots of variations of how people made single phase motors spin, because they won’t do so naturally. Eventually the methods used now won out and a lot of the more complicated and cumbersome versions died out. This looks like one of those early attempts, probably something akin to a “Repulsion Start / Induction Run” motor. RS/IR motors started like a DC motor but had a moving set of brushes that pulled away based on centrifugal force at which point they ran as induction motors.

Perspective can be very deceiving! In that first photo, the box on the motor appears to be taller than the car! How big is the motor?

I' ve seen a lot of motors, but none like that!

L'ANGELUS refers to bells in the Catholic Church that are rung three times a day. This may be a timing motor and possibly a driver for bell ringing.

I think you're right, it's an old French electric bell ringer motor...

Great find!

Please post an update if/when you have it running.

Thanks for the input. My research also pointed to a bell ringer. I will carefully dismantle it, repair the wiring and hopefully it will run. As a collector of old iron I consider this a great find.

I have seen similar construction,but not this exact motor.

The coils and contacts in the top photo are for reversing the direction of motor rotation.

The contacts in the bottom photo are there to prevent reversal of direction while motor is still in motion.

The pointer is used to indicate the proper tension of the contacts when motor is stopped.

In a single phase motor,if it is still in motion,the reversing switch will have no effect on the direction of motion.This can be very dangerous in certain situations.

For example,a chain hoist that is moving up is suddenly reversed before it stops will continue to go up until it jams and possibly strips the gear works or trips out the overload and could possibly drop the load.

Later models used a relay to accomplish this.
