Electric Motor Manufacturers
Electric motors function by using the interaction of an electrical current and a magnetic field in order to produce mechanical force, or energy. Through the use of electrical energy in the form of either an alternating current (AC) or a direct current (DC), electrical motors are capable of powering various types of machinery.
Categorized by many different means, the four main ways of categorizing electric motors are: the source of electric power, the internal construction, the type of motion they provide and their application. As a result, although electric motors can be divided into AC motors and DC motors (although universal motors that operate on both types of electrical currents tend to mess with that easy division) there are many more possibilities of categorization. Due to the wide range of electric motor types, there are a vast number of applications and industries that utilize them including: construction, in order to power varied machine and power tools; industrial manufacturing, used as industrial motors to power various manufacturing, processing and automation equipment; electronics, to power electrical devices such as hard drives, CD players, DVD players and more; residential, to power household appliances such as fans, clocks and exercise equipment; and office, for various equipment such as printers, computers and fax machines.

While all electric motors provide the same basic function of converting electrical energy to mechanical energy, the method by which they convert the energy can differ greatly. In terms of conversion methods, there are four main types of electric motors: servo motors, synchronous motors, induction motors and electrostatic motors, which are also referred to as capacitor motors. Servo electric motors operate based on a servomechanism (often shortened simply to servo) that utilizes error-sensing feedback to function and make corrections. Servo motors are extremely small electric motors and are often utilized in robotics, such as remote-controlled cars. Synchronous electric motors are a type of AC motor that operate based on a rotating magnetic field that is the result of the motor’s rotor and current passing at the same rate. Much like synchronous motors are induction motors, which are fairly identical except that induction motors are asynchronous, even at times being referred to as asynchronous motors instead of induction motors. Induction motors operate based on the principle of electromagnetic induction in which a voltage is produces across a conductor, being the rotor, as it is moving through a magnetic field. Lastly, electrostatic motors are very different than the others, and instead operate based on the principle of the attraction and repulsion of an electric charge. Electrostatic motors are often used in very small-scale applications such as in micro-mechanical systems (MEMS).
Other than the method by which they convert electrical energy to mechanical energy, electric motors are also classified by means of the type of motion. Some common electric motors that fall under those classifications include: 3 phase motors, single phase motors, 12V motors, stepper motors and linear motors. 3 phase motors are typically a type of induction motor, and offer both high efficiency and a fairly simple design. 3 phase motors operate by means of a set of three alternating currents that are used to distribute the newly converted mechanical energy. Also commonly a type of induction motor, single phase motors operate based on a single-phase power source meaning that there is only one source of the electrical current, which is an AC. While still referring to the power source, 12V motors are categorized by the measurement of their power source and not the method of powering. One of the most common types of electric motors, 12V motors operate based on the standard 12 voltages of electric power. Stepper motors, on the other hand, are incredibly similar to three-phase synchronous motors. The main difference between those motors and a stepper motor is that stepper motors do not rotate continuously. Instead, stepper motors must continuously start then stop and start and then stop again and again. Finally, there are linear motors which are basically defined by the type, or really direction, of mechanical energy that they provide. Since a linear motion is motion that occurs over a straight line, linear motors can be defined as electric motors that provide motion over a single plane.
When categorizing based upon the construction of the electric motor, there are two main categories: brushed motors and brushless motors. Brushed electric motors can be easily determined based upon the design of the motor. A brushed motor is typically a type of DC motor, and operates based upon the actions of a wound rotor (also known as an armature), a commutator, and a permanent or wound magnet stator. The motor gets its name from the commutator, which is equipped with numerous brushes. These brushes operate by allowing the current to flow through them and thus arrive at the wound rotor. There are five main types of brushed motors: DC shunt wound motors, DC series wound motors, DC compound motors, permanent magnet DC motors and separately-excited motors. Capable of operation without the use of brushes to transfer the electrical current, brushless electric motors are also most often a type of DC motor. Whereas brushed motors can run into some problems due to their more complicated design, brushless motors eliminated many of those issues. Brushless motors consist of a permanent magnet external rotor, a three-phase coil, a type of sensor and drive electronics. Instead of brushes, brushless motors transfer the current by means of the sensors, called Hall effect sensors.
