Question 1: The same Hall effect sensors that provide the commutation can also provide a convenient ________ signal for closed-loop control (servo-controlled) applications. | |||
|
Question 2: Operating at normal power line frequencies, universal motors are very rarely larger than one kilowatt (about 1.3 ________). | |||
|
Question 3: Another common application is the control of the throttle of an internal combustion engine in conjunction with an ________ governor. | |||
|
Question 4: A linear motor is essentially an electric motor that has been "unrolled" so that, instead of producing a ________ (rotation), it produces a straight-line force along its length by setting up a traveling electromagnetic field. | |||
|
Question 5: In 1882, ________ discovered the rotating magnetic field, and pioneered the use of a rotary field of force to operate machines. | |||
|
Question 6: [12] Due to the high cost of the ________ electrodes required by primary battery power, the motors were commercially unsuccessful and the Davenports went bankrupt. | |||
|
Question 7: Pancake motors are still widely used in high-performance servo-controlled systems, humanoid ________ systems, industrial automation and medical devices. | |||
|
Question 8: Electric motor, Nikola Tesla and Three-phase electric power are all:
|
|||
|
Question 9: You can find a linear motor in a maglev (________) train, where the train "flies" over the ground, and in many roller-coasters where the rapid motion of the motorless railcar is controlled by the rail. | |||
