Best Answer

A series dc motor does not have a well defined maximum speed, which depends on the friction in the bearings. It is dangerous to run this type of motor without a load because it could be damaged by excessive speed.

Series motors are normally attached to massive loads, like trams or trains, which limits the speed, and the very high starting torque is useful for traction because it removes the need for a gearbox.

How do you tell if a motor is 115V or 230V?

First and foremost you should look at the nameplate. If the nameplate is unreadable then you will do no harm plugging it into a 115 volt supply. If the motor looks like it is running at full speed then it is a 115 volt motor. If you plug it in and it looks like the shaft is turning at about half speed then it is a 230 volt motor. If the motor is running slow don't leave it plugged in for more that 15 seconds. Find a 230 volt supply and plug it in, it should run at the right speed. If you have a shaft tachometer use it on the end of the shaft to get an accurate rotation speed. The above prompted comparison with another motor, with the same RPM rating, allowing a simple feel of the shafts for a close speed match. The help is appreciated.


What would cause the windshield wipers to freeze in position when the switch is flipped to the high speed and how can they be repaired?

I have a 94 caprice that does this. Apparently it is either that speed only on the wiper motor that has a problem or the relay for the high speed may have failed and the motor may be ok. As it is a noncritical issue I haven't worried too much about it. If I find out more I will update this.
