MOTOR TERMS
This stationary part of an AC motor contains the windings that produce the rotating magnetic field.
What is the stator?
This team plays its home games at Lambeau Field.
Who are the Green Bay Packers?
This device disconnects the starting winding of many single-phase motors once the motor reaches a certain speed.
What is the centrifugal switch?
This is the month when MLB's World Series is traditionally played.
What is October?
This instrument is used to determine the rotation order of the phases in a three-phase system.
What is a phase-sequence meter?
This rotating part of a motor is connected to the shaft and interacts with the stator's magnetic field.
What is the rotor?
This NFL position is usually responsible for throwing the football.
What is quarterback?
In a capacitor-start motor, this winding has the higher current during the starting period and is then disconnected.
What is the starting/auxiliary winding?
This team plays its home games at Wrigley Field
Who are the Chicago Cubs?
If a winding-to-winding resistance test on a three-phase motor shows one winding substantially different from the others, this could indicate a winding problem.
What is a shorted, open, or damaged winding?
This motor has rotor windings connected to slip rings, allowing external resistance to be added to the rotor circuit.
What is a wound-rotor motor?
This team defeated the Miami Dolphins 24–10 in Week 3.
Who are the Kansas City Chiefs?
To reverse a typical three-phase motor, you swap any two of these.
What are any two of the three phase conductors?
This team plays its home games at Yankee Stadium.
Who are the New York Yankees?
This condition occurs when one phase of a three-phase motor is lost while the motor is still connected to the supply.
What is single-phasing?
In this type of three-phase motor, the rotor consists of conductive bars connected by end rings and has no electrical connection to the outside.
What is a squirrel-cage motor?
This team plays its home games at Soldier Field and is scheduled to play Philadelphia on Monday Night Football this week.
Who are the Chicago Bears?
In an induction motor, this quantity is the difference between synchronous speed and actual rotor speed, usually expressed as a percentage of synchronous speed.
What is slip?
This MLB player is famous for being a two-way star who both pitches and hits.
Who is Shohei Ohtani?
A motor that draws extremely high current while its rotor is unable to turn is experiencing this condition.
What is locked-rotor current?
This NEMA motor design is known for very high starting torque, high slip, and applications such as crushers, conveyors, and compressors.
What is NEMA Design D?
This NFL team won Super Bowl LX in February 2026.
Who are the Seattle Seahawks?
A three-phase motor has a 60 Hz supply and operates at 1,740 RPM on a four-pole system. This phenomenon allows the rotor to turn slightly slower than synchronous speed.
What is slip, caused by the difference between rotor speed and synchronous speed?
This is the name given to MLB's championship series between the American League and National League champions.
What is the World Series?
An industrial facility wants to improve its power factor. Adding appropriately sized capacitors is one common method because they supply this type of reactive power locally.
What is capacitive reactive power?
