Usage/Application | Motor Starting |
Brand | National Resistors |
Mounting type | Through Hole |
Country of Origin | Made in India |
Tolerance | +/-10% |
Voltage Rating | As per Rotor Voltage of Motor |
We National Resistors manufacture Resistance Boxes used for heavy duty requirement of starting and for speed control of electrical motors.
Motor Starting Resistors are used to reduce the voltage at the motor terminals and also decrease the starting current. Motor Starting Resistors are necessary because the self resistance of a motor armature is very low. With this gradually increasing torque and voltage, the acceleration becomes smooth.
This resistor allows a stepped starting having high starting torque with low and limited starting currents. Suggested for high power motors and to drive equipments with strong inertia and needs of fast accelerations and heavy, long and frequent startings
This resistor is used for gradual starting with the possibility to choose the torque in relation with the device to start. Suggested for equipments with low starting torque and increasing advancement.
