|
Powder Brakes /Clutches are proportional Torque devices. Torque is controlled by varying the excitation current. Torque is strictly proportional to excitation. These devices has minimal drag torque, i.e. at zero excitation, torque is minimal and near to zero. This devices are for high torque – low power applications.
Powder Brake & Clutches are manufactured by us in wide range Torque rating starting from tiny 0.3 KgM to massive 100 KgM, & comes in self cooled, forced cooled and water cooled models.. These devices come with matching electronics to meet your most exacting applications |

8.) TACHOGENERATOR |
|
Tachogenerator is a device which generates an electrical output directly proportional to the shaft speed. The voltage thus generated is fed to a speedometer for speed measurement and/or used as feed - back signal for controlling the speed of a rotating machine / equipment. In every automatic control system, since the system performance is directly related to the performance it becomes essential that the Tachogenerator must satisfy certain minimum requirements such as:
|
Linear
The rectified output voltage should be strictly linear with respect to the rotational speed
Output signal
the ripple content in the rectified output signal must be as low as possible
Temperature effect
Variations in ambient temperature should have negligible effect on the TG output
Long-term stability
Instability of output cause due to aging of parts, shift in magnetic circuits etc., should be minimum.
Unique features of Tachogenerator
• ALINCO permanent magnet in the rotor assembly gives long term stable operation under varying ambient temperature.
•
Large number of poles (48) results in a high frequency output and hence good dynamic response, linearity and wide speed control, along with low ripple content in the rectified output.

CERBACK is suitable for ship building, marine facilities, plants and other steel structures and is widely used for one side welding technique such as CO2 semiautomatic welding and automatic welding. |
 |
Product Feature
CERBACK is a fine ceramic product composed of adequately mixed natural
inorganic substances (kaolin, talc, alumina, magnesia etc.) that are heat-treated
at high temperatures of 1,350ºC~1,400º C span.
Since CERBACK is heat-treated at high temperatures its shock resistance to
rapid heating and cooling is excellent (coefficient of thermal expansion is 1.85- 2.5 x 10-6
at 1,000º C ) and maintains superb stability against the high
temperatures created good beads on the back side.
CERBACK has excellent characteristics of ceramic such as anti-acid, anti chemicals.and anti-corrosion and also caused no change or reaction of steel at
the time of welding. |
