WebAs your current speed is 1750rpm, however, I assume that your motor is asynchronous. Therefore, you can decrease your effective speed by using a rheostat, as long as your slip is low enough to keep your motor running. Obviously, you'll still decrease your system efficiency. In my opinion, you should go for VFD: for a 1.12kW motor, this is cheap. Web20 dec. 2012 · Signaling by cell surface receptors appears to be relatively straight-forward: ligand binds to the extracellular domain of the receptor and biochemical changes are communicated into the cell.
