When Baldor Motor Corporation provides customers general motors, it also can supply complete series servo products and sport control products, including servo motor, motor controller, brushless motor controllers, servo motor controllers, stepper motor controllers etc. at the same time, costomize special motor according to clients’ requirement also is a easy task for the company. Nearly 200 development’s history make the company has become the second largest motor manufacture in the world, and the annual production also is surprising: the total number of various motors has reached 1000 millions units each year.  Because of the high reputation of the company and the high quality of the products, many customers prefer to spend relative high price in buying baldor’s products.

The rotation motor with the definition of output or input is direct current named the DC motor, it is a kind of motor can achieve current energy and mechanical energy DC electrical motor interchangeable. When it used for motor it was regarded as dc motor, which will convert electrical energy to mechanical energy; when use for generator, it is dc generator which convert the mechanical energy into electricity energy.

The structure of DC motor should be composed of stator and rotor two parts. When DC brush motor running, the stationary part is called the stator, and the main function of stator role is to produce magnetic field. Naturally, the rotating part of the runtime is called the rotor, and its main role is to generate the electromagnetic torque and induced electromotive force, it is called the armature because it is the hub of energy conversion.

The world’s earliest Prototype motor is permanent magnet electrical motor, but because the performance of permanent magnetic materials in that time was poor, so electromagnetic motors have been accounted for the mainstream. The birth of Alnico permanent magnet made the permanent magnet motor to start the advent of development, but because of its relatively high price, the application surface of Alnico magnet motor is not widespread. Since the emergence of low-cost ferrite, the application of permanent magnet motor substantially increases. According to statistics, among DC motor below 500W, the permanent magnet motor accounts for more than 92%, most of which is ferrite permanent magnet brush motor. The emergence of samarium cobalt permanent magnet makes high-performance servo motor to be achieved.
