  Definite and Special-Purpose Motors

  be checked very closely against the load. Testing the motor with the application is recommended. Instrument motors. Instrument motor definitions vary with users and manufacturers of motors. Generally, an instrument motor is a precision motor with fractional or subfractional horsepower ratings. Sizes range from 1/2 to 3/4hp units. Toothless motors. Some motors can be made with toothless armatures, thanks to powerful modern magnets. Coils are wound and assembled outside the motor, then inserted... (read more)

  Synchronous Motors

  or polyphase, cannot start without being driven, or having their rotor connected in the form of a self-starting circuit. Since the field is rotating at synchronous speed, the motor must be accelerated before it can pull into synchronism. Accelerating from zero rpm requires slip until synchronism is reached. Therefore, separate starting means must be employed. In self-starting designs, fractional horsepower motors use methods common to induction motors (split phase, capacitor-start, and shaded...

  Induction Motors

  inertia load. External resistance gives the motor a characteristic that results in a large drop in rpm for a fairly small change in load. Reduced speed is provided down to about 50%, rated speed, but efficiency is low. Single-phase motors. These motors are commonly fractional-horsepower types, though integral sizes are generally available to 10 hp. The most common single phase motor types are shaded pole, split phase, capacitorstart, and permanent split capacitor. Shaded pole motors have... (read more)

  and currents, and low slip. Fractional-horsepower polyphase ac motors are generally design B. Because of the drooping characteristics of design B, a polyphase ac motor that produces the same breakdown (maximum) torque as a single-phase ac motor cannot attain the same speed-torque point for full-load speed as single-phase ac motors. Therefore, breakdown torque must be higher (a minimum of 140% of the breakdown torque of single-phase, general-purpose ac motors) so that full-load speeds are comparable... (read more)

  Custom DC Motors

  normally as fractional-horsepower dc motors. Dc motors may be further classified for intermittent or continuous duty. Continuous-duty dc motors can run without an off period. DC Motors - Speed control. There are two ways to adjust the speed of a wound-field dc motor. Combinations of the two are sometimes used to adjust the speed of a dc motor. DC Motor - Shunt-field control. Reel drives require this kind of control. The dc motor's material is wound on a reel at constant linear speed and constant... (read more)

  Induction Motors

  The induction motor is the most commonly used type of ac motor. It's simple, rugged construction costs relatively little to manufacture. The induction motor has a rotor that is not connected to an external source of voltage. The induction motor derives its name from the fact that ac voltages are induced in the rotor circuit by the rotating magnetic field of the stator. ARC's complete lines of AC Induction Motors are manufactured using a squirrel cage rotor utilizing both aluminum and copper... (read more)
