The most common DC drives are for ? motors.
shunt-wound
A ? gear is a gear with teeth that are not parallel to the shaft axis.
helical
How many yards does Saquon Have (playoffs included)
2447
Temperature changes resulting in thermal expansion may be caused by the ? .
a. heat from a loaded motor
b. high ambient (room) temperature
c. temperature of the pumped product
d. all of the above
A(n) ? is when current leaves its normal path and travels to the frame of the motor.
ground fault
? drives can be used to control most types of induction and synchronous motors, and several motors can be operated at the same time.
Variable-voltage-inverter
A ? gear is a gear with straight tapered teeth used in applications where shaft axes intersect.
bevel
How many yards until saquon breaks the rushing record (including playoffs)
29 to tie
30 to break it
A drilled and tapped base plate that is used to anchor a machine must have a minimum thickness of ? times the root diameter of the anchoring bolts.
1-1/2
A(n) ? circuit is an electrical circuit that has an incomplete path that prevents current flow.
open
? bearings contain an outer ring (cup) and rollers that are retained in a cage and bear directly on the rotating shaft.
Needle
A(n) ? clutch generally can control the torque over only a limited operating range but is well suited for hoists and cranes.
friction
how many super bowls have the birds been to?
5
? soft foot is prevented by using clean, solid bases with all paint, grime, rust, and corrosion thoroughly removed.
Springing
Before troubleshooting an electrical control circuit, an individual must understand the ? .
a. operation of the circuit
b. sequence of events
c. timing and counting functions
d. all of the above
A ? containing gear teeth is used for synchronous drive systems.
timing belt
Using a clutch to disconnect the load from the motor shaft allows the motor to be started at ? .
no load

Jalen Hurts
LeGarrette Blount
Laser alignment devices operate using the ? method.
rim-and-face
A dual-voltage, wye-connected motor has ? separate stator winding circuits.
Note: This is not the number of total leads in the connection box.
4
A ? is used to protect gears from the surrounding environment and to change shaft rotation, speed, and/or direction of rotation.
gearbox
A(n) ? is a rigid steel support for firmly coupling and aligning two or more rotating devices.
base plate

Wrong
A ? wears faster than any other component of a DC motor.
brush
A ? motor uses voltage and current pulses to control movement of a load.
