DC Motors & Controls
TEMCo's broad range of DC products includes brand names like Baldor DC motors through 500 hp, with custom capabilities of 700 hp and DC controls ranging from sub-fractional horsepower to 600 hp.
DC Motors - TEMCo's DC motors include fractional permanent magnet SCR drive motors, as well as larger shunt and stabilized shunt wound blower-ventilated DC motors to 500 hp.
The Basics of a D.C. motor is a permanent magnet is positioned around a loop of wire that is hooked up to a D.C. power source. To make the loop of the wire spin, a battery or DC power supply is connected between its ends, and support it so it can spin about its axis. The ends of the wire loop are connected to a set of contacts call commutator to allow the rotor to turn without twisting the wires. These commutators rub against a set of conductors called the brushes. As the commutator spins the brushes making electrical contact. They are connected to the positive and negative leads of the power source, this allows electricity to flow through the loop. The electricity flowing through the loop creates a magnetic field that interacts with the magnetic field of the permanent magnet to make the loop spin.
Advantages of DC Motors
The biggest advantage of DC Motors may be speed control. Speed is directly proportional to armature voltage and inversely proportional to the magnetic flux produced by the poles, adjusting the armature voltage or the field current will change the rotor speed. Adjustable frequency drives are used to provide precise speed control for AC motors, but this effect the power quality, as the switching devices in the frequency drives produce a rich harmonic spectrum. However, the DC motor has no adverse effects on power quality. The construction of a DC motor is more complicated and expensive than that of an AC motor, mainly due to the commutator, brushes, and armature windings. Furthermore, the maintenance of the brushes and commutator means more maintenance on a DC motor.
Applications For DC Motors
In spite of the drawbacks of DC Motor such as power supply, initial cost, and maintenance requirements the DC motors are widely used particularly in applications like cars and small appliances. The following are some uses of the DC motors.
