Hello all,
Have a newbie question for you. I'm trying to get a small shaded pole motor hooked up to a motion sensor, with no success. Here are links to the components involved:
Motor: http://www.mcmaster.com/#6142k54/=oajcig
115/60 v/hz 1amp @ full load
Sensor: http://heath-zenith.hcents.com/data/manuals/595-5109-13.pdf
120/60 v/hz---- 4.2 amp / max 500 watt across white pole. I'm assuming that means it's max load.
So here is whats happening, when the motor is plugged straight into the wall socket it operates fine. However when I hook it up, roughly following the schematics on the heath-zenith pdf, adding only a switch on the hot leg as it comes from power, the motor spins extremely slowly, if at all. And also begins to heat up rapidly. Small incandesent light bulbs work fine as well as another 1/60 hp .8 amp motor (works mostly fine, different style motor altogether however).
I know there are obviously power compatibility issues between the sensor and motor at fault here but I'm having trouble reasoning them out. If the sensor can produce a 500 watt switch, while the motor only needs roughly 1amp x 115v = 115watts at full load to operate normally, why is it acting like its getting more than it can handle? Conversely when hooked directly up to building power, when it's getting like 15+amps or 1800watts why does it act correctly? Seems like in the second scenario it would be worse.
Anyways I'm obviously new at this and could use some clarification on the circuit, the power going in and out of the sensor, and what it all means. I'm not sure if I need to research a relay or some type of resistor to control the power into the motor. And where/what that component would be. Rationalizing it out after writing this, it seems like a 1 amp resister on the hot leg as it leaves the sensor would bring the line amp down to the motors max load rating, not sure that would help though. IDK.
Any help would be appreciated.
best
