Motors

An electric motor converts electrical energy into mechanical energy. Most electric motors operate through interacting magnetic fields and current-carrying conductors to generate force, although electrostatic motors use electrostatic forces. The reverse process, producing electrical energy from mechanical energy, is done by generators such as an alternator or a dynamo. Many types of electric motors can be run as generators, and vice versa. For example a starter/generator for a gas turbine, or traction motors used on vehicles, often perform both tasks. Electric motors and generators are commonly referred to as electric machines.

Electric motors are found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives. They may be powered by direct current (e.g., a battery powered portable device or motor vehicle), or by alternating current from a central electrical distribution grid. The smallest motors may be found in electric wristwatches. Medium-size motors of highly standardized dimensions and characteristics provide convenient mechanical power for industrial uses. The very largest electric motors are used for propulsion of ships, pipeline compressors, and water pumps with ratings in the millions of watts. Electric motors may be classified by the source of electric power, by their internal construction, by their application, or by the type of motion they give.

AC Motors

An AC motor is an electric motor driven by an alternating current. It commonly consists of two basic parts, an outside stationary stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft that is given a torque by the rotating field. Where speed stability is important, some AC motors (such as some Papst motors) have the stator on the inside and the rotor on the outside to optimize inertia and cooling.

Other Common names for AC Motors are: Single Phase Induction, Three Phase Induction, Split Phase Induction Motor, Synchronous, Three Phase AC Synchronous Motor, Shaded-pole synchronous, Doubly Fed, Shaded Pole, Linear, Direct drive, Lynch, Drum, Mush winding, Slip Ring, Wound Rotor, Gear, Permanent-split capacitor Motor

Below are some common AC motor manufacturers. If your motor is not listed, do not worry, we can still fix it. Just give us a call.

Servo Motors

Servo motors are electric motors that have some kind of built in feedback mechanism. The servo motor can tell the servo drive when an error or anomoly has occurred, thus allowing it to be corrected without operator intervention.

Servo motors are used in applications where exact motion is required, such as in robotics or extremely fine machining centers. The more complex the machine is, the more often errors occur.

REA Technologies are experts in the troubleshooting and repair of servo systems. We can repair both the Servo drive and Servo motor, as well the critical feedback units that make them special. We have hydraulic specialists that can help you troubleshoot and set up your servo assisted hydraulic system also.

Other common names for Servo Motors are: Feedback motor, RC servo motor, AC servo motor, DC servo motor, DC brushless servo motor, Fractional horsepower motor.

Below you will find a list of servo motor manufacturers that we have experience working with.

If you do not see your servo motor's manufacturer listed, call us. We can repair it for you.

Spindle Motors

A spindle motor is a small, high-precision, high-reliability electric motor that is used to rotate the shaft, or spindle. Most often the motors attached to machine tool heads are spindle motors. They are usually relitively small, high speed, high torque, motors and can be attached to a gearbox to change the speed of the motor's output. They are usually controlled by dedicated Spindle Drives.

Other common names for spindle motors are: High Precision, and Ultra High Precision motors.

REA Technologies can repair your spindle motor if it is having problems.

We have worked on Spindle drives manufactured by:

Stepper Motors

A stepper motor (or step motor) is a brushless, synchronous electric motor that can divide a full rotation into a large number of steps. The motor's position can be controlled precisely without any feedback mechanism (see Open-loop controller), as long as the motor is carefully sized to the application. Stepper motors are similar to switched reluctance motors, which are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.

Stepper motors operate differently from DC brush motors, which rotate when voltage is applied to their terminals. Stepper motors, on the other hand, effectively have multiple "toothed" electromagnets arranged around a central gear-shaped piece of iron. The electromagnets are energized by an external control circuit, such as a microcontroller. To make the motor shaft turn, first one electromagnet is given power, which makes the gear's teeth magnetically attracted to the electromagnet's teeth. When the gear's teeth are thus aligned to the first electromagnet, they are slightly offset from the next electromagnet. So when the next electromagnet is turned on and the first is turned off, the gear rotates slightly to align with the next one, and from there the process is repeated. Each of those slight rotations is called a "step", with an integer number of steps making a full rotation. In that way, the motor can be turned by a precise angle.

Other popular names for Stepper motors are: Unipolar stepper, Bipolar stepper, Full stepper, Half Stepper, Microstepping, Permanent magnet stepper, Variable reluctance stepper, Hybrid stepper, Brushless Stepper Motor, Open Loop Stepper Motor, Closed Loop Stepper Motor .
