The synchronous speed of a motor is determined by the number of poles a motor has, and the ____________ of the current being supplied to it.
Which component of a solid state reduced voltage starter is identified in red on the pictured line diagram?
This method of reduced voltage starting replaces mechanical components with electronic components.
Which type of motor control is used when the application calls for the need to ramp speed when the motor is turned on, but not during the run of the application?
The _________________ allows the operator to command the motor to function as desired, through the use of motor control inputs and outputs.
Arcing and contact bounce are two areas of concern for contact life in full voltage motor control. 
One reason for using reduced voltage starting is to avoid stress on equipment or product lines.
This starter type connects the incoming power to the motor, in one direction at one speed.
Which overload relay is made up of two strips of different metals?  The dissimilar metals are permanently joined and heating the strip causes it to bend as the dissimilar metals expand and contract at different rates.
