- I have a standard blow with a standard 115V single phase "four
- speed" motor on it. The label on the motor says it is a 1050RPM motor with
- four speeds. The problem is that all four speeds are about the same.
- My questions are as follows:
-
- 1. If label RPM is 1050 what are the other 3 speeds, higher, lower
- on each side or what?
-
- 2. I thought motors come in 1050, 1175 or 3000 something, other
- speeds were gotten with a rheostat or pulley system...
-
-
- Anyhelp would be appreciated...
