Quality is the key word at Industrial Electrical Company; quality in new motors. Our New Products Sales division offers complete lines of AC and DC motors from manufacturers such as Baldor, Leeson, US Motors, SEW Eurodrive, AC Tech, Sumitomo, Tatung, Teco, and Sterling.AC MOTORSAC motors typically feature rotors, which consist of a laminated, cylindrical iron core with slots for receiving the conductors. The most common type of rotor has cast-aluminum conductors and short-circuiting end rings. This ac motor "squirrel cage" rotates when the moving magnetic field induces a current in the shorted conductors. The speed at which the ac motor magnetic field rotates is the synchronous speed of the ac motor and is determined by the number of poles in the stator and the frequency of the power supply: ns = 120f/p, where ns = synchronous speed, f = frequency, and p = the number of poles.DC MOTORSDc motors are often applied where they momentarily deliver three or more times their rated torque. In emergency situations, dc motors can supply over five times rated torque without stalling (power supply permitting).Dynamic braking (dc motor-generated energy is fed to a resistor grid) or regenerative braking (dc motor-generated energy is fed back into the dc motor supply) can be obtained with dc motors on applications requiring quick stops, thus eliminating the need for, or reducing the size of, a mechanical brake. Dc motors feature a speed, which can be controlled smoothly down to zero, immediately followed by acceleration in the opposite direction -- without power circuit switching. And dc motors respond quickly to changes in control signals due to the dc motor's high ratio of torque to inertia. -------------------------------------------------------------------------------- ToshibaThe Industrial Division is a world leader in the design and manufacture of motors, motor controls and power electronics products. Many of these products are designed, built and tested in our 620,000 square foot state-of-the-art manufacturing facility in Houston. We have developed a totally integrated manufacturing process from research and development, design, engineering, production and manufacturing to after-market service and support. At the heart of this process is our unrelenting belief in quality and reliability. We build products to perform in the most difficult conditions. From raw material to the finished product, we assure exacting quality, engineering excellence and stringent testing to meet domestic and international performance standards. These high standards result in long-lasting, highly reliable products. This standard of quality and reliability stems from our dedication to delight our customers. We work to meet and exceed customer expectations by providing superior products and services. |
