  Jones on Stepping Motors
Typically, all windings in the motor are part of the stator, and the rotor is either a permanent magnet or, in the case of variable reluctance motors, a toothed block of some magnetically soft material.
All of the commutation must be handled externally by the motor controller, and typically, the motors and controllers are designed so that the motor may be held in any fixed position as well as being rotated one way or the other.
For example, the repeatability of positioning done with a stepping motor depends on the geometry of the motor rotor, while the repeatability of positioning done with a servomotor generally depends on the stability of the potentiometer and other analog components in the feedback circuit.

  Electric motor - Encyclopedia.WorldSearch   (Site not responding. Last check: )
The speed of the motor is proportional to the voltage, and the torque is proportional to the current.
The speed of the AC motor is determined primarily by the frequency of the AC supply, whereas the torque is determined by the amount of slip, or difference in rotation, between the rotor and stator fields.
A stepper motor is a cross between a DC electric motor and a solenoid.

 Electric motor - Wikipedia, the free encyclopedia
The modern DC motor was invented by accident in 1873, when Zénobe Gramme connected a spinning dynamo to a second similar unit, driving it as a motor.
Closely related in design to three-phase AC synchronous motors are stepper motors, where an internal rotor containing permanent magnets or a large iron core with salient poles is controlled by a set of external magnets that are switched electronically.
A stepper motor may also be thought of as a cross between a DC electric motor and a solenoid.

Full-load motor torque is calculated to determine the required braking torque of a motor.
This is because the synchronous speed of an induction motor is based on the supply frequency and the number of poles in the motor winding.
Motor are designed for 60 hz use have synchronous speeds of 3600, 1800, 1200, 900, 720, 600, 514, and 450 rpm.

Total impulse is a measure of the overall total energy contained in a motor, and is measured in Newton-seconds.
As a rule of thumb, the thrust duration of a motor can be approximated by dividing its total impulse by its average thrust.

To replace a motor it is necessary to remove the blower wheel or fan blade from the motor.
As far as ratings are concerned do not replace a motor with one of a smaller horsepower ratting but know that a larger motor will waste energy because motors are most efficient when loaded to 80- 90%.

Most motors have a fixed outer portion called the stator, which creates the stationary magnetic field, and a rotor, which is wrapped in a wire coil.
Energy-efficient AC motors produce the same output as standard motors, but require less electrical input because they generally are better designed, with better materials and improved manufacturing quality.
When purchasing a new motor or replacing a failed one, paying extra for the efficient model is a good investment simply because a motor consumes energy worth 4 to 10 times its own initial cost each year.

The Ford Motor Company (often referred to simply as Ford; sometimes nicknamed FoMoCo, NYSE: F is an automobile maker founded by Henry Ford in Dearborn, Michigan, and incorporated on June 16, 1903.
The Ford Motor Company has denied allegations that they profited by the use of forced labor to produce tanks for the Nazis during the war, saying that Ford had lost control of the German division by that point in the war and was not responsible for its activities.
Increasingly, Ford Motor Company has looked to Ford of Europe for its 'world cars', such as the Mondeo, Focus, and Fiesta, although sales of European-sourced Fords in the US have been disappointing, and in Asia, models from Europe are not as competitively priced as Japanese-built rivals, nor are they perceived as reliable.

 Glossary of Motor Terms -"I"- B-9652-4
An induction motor is an alternating current motor in which the primary winding on one member (usually the stator) is connected to the power source and a secondary winding or a squirrel-cage secondary winding on the other member (usually the rotor) carries the induced current.
Since there are various ambient temperature conditions a motor might see and different temperature ranges within which motors run and insulation is sensitive to temperature; motor insulation is classified by the temperature ranges at which it can operate for a sustained period of time.
When a motor insulation class is labeled on the nameplate the total insulation system is capable of sustained operation at the above temperature.

 Motors   (Site not responding. Last check: )
Electric vehicle drive motors can be divided into two basic groups, DC or direct current motors, and AC or alternating current motors.
The most commonly used version is what is known as a series-wound motor, which means the armature and field windings are wired in series.
At the present time AC motors are most commonly found in commercially built EVs, as they require more sophisticated and complex control systems than DC motors.
