- Company Profile:
The portion of a gearmotor which contains the actual gearing which converts the basic motor speed to the rated output speed.
Industry:Electrical equipment
A mechanical device for engaging and disengaging a motor often used when many starts and stops are required.
Industry:Electrical equipment
A gearhead and motor combination to reduce the speed of the motor to obtain the desired RPM's.
Industry:Electrical equipment
A material, such as copper or aluminum, which offers low resistance or opposition to the flow of electric current.
Industry:Electrical equipment
A general-purpose motor is any motor having a "B" design, listed and offered in standard ratings with standard operating characteristics and mechanical construction for use under usual service conditions without restriction to a particular application or type of application. (NEMA
Industry:Electrical equipment
The metal container usually on the side of the motor where the stator (winding) leads are attached to leads going to the power supply.
Industry:Electrical equipment
A motor with an electrical connexion between the motor frame and ground.
Industry:Electrical equipment
A term used to describe non-uniform angular velocity. It refers to rotation occurring in jerks or increments rather than smooth motion. When an armature coil enters the magnetic field produced by the field coils, it tends to speed up and slow down when leaving it. This effect becomes apparent at low speeds. The fewer the number of coils, the more noticeable it can be.
Industry:Electrical equipment
An open motor in which all openings giving direct access to live or rotating parts (except smooth shafts) are limited in size by the design of the structural parts or by screens, grills, expanded metal, etc., to prevent accidental contact with such parts. Such openings shall not permit the passage of a cylindrical rod 1/2 inch in diameter.
Industry:Electrical equipment
The electrical conductors wound into the core slot, electrically insulated from the iron core. These coils are connected into circuits or windings which carry independent current. It is these coils that carry and produce the magnetic field when the current passes through them. There are two major types: "Mush" or "random" wound, round wire found in smaller and medium motors where coils are randomly laid in slot of stator core; and formed coils of square wire individually laid in, one on top of the other, to give an evenly stacked layered appearance.
