Advantages of Starting and Adjusting Resistor Box
High precision
The resistance value of the resistance box usually has a high precision. Common precisions are 1%, 0.1%, 0.05%, etc., which can meet various test and calibration requirements.
Wide range
The resistance value range of the resistance box is relatively wide, generally reaching tens of ohms to hundreds of megohms.
Good stability
The resistance value of the resistance box is generally stable and is not affected by ambient temperature, humidity, etc.
Easy to operate
The use of the resistor box is relatively simple. Generally, you only need to rotate the pointer of the resistor box according to the instructions or the label to get the desired resistance value.
Application Areas of Speed Control Resistor
Power Industry
In power generation facilities such as thermal power plants, hydroelectric power plants, and nuclear power plants, Starting And Adjusting Resistor Boxes are used to start and adjust the motors of auxiliary equipment such as large fans, water pumps, and coal mills, ensuring stable operation during power generation.
Metallurgical Industry
In metallurgical enterprises such as those involved in steel and nonferrous metals, resistor boxes are widely used to control the motors of rolling mills, steelmaking furnaces, fans, and pumps, meeting the precise starting torque and operating speed requirements of motors in metallurgical production.
Chemical Industry
The starting and adjusting of motors for various pumps, compressors, mixers, and other equipment in chemical production processes rely on resistor boxes. They ensure smooth starting and reliable operation of equipment in complex chemical environments, ensuring safe and efficient chemical production.
Resistor Selection Criteria
When considering resistors in electric motor control applications, resistor value, physical dimensions, power rating, tolerance temperature and voltage coefficient (TCR/VCR), frequency performance and resistor stability are all issues to consider.
In motor control applications dimensions, and frequency performance is generally not an issue. In many applications, tolerance and TCR/VCR are minor considerations. They are important, however, in current sense resistors.
When choosing an inrush resistor for electric motor power management applications, it is important to ensure it can both withstand the maximum inrush current and the energy generated by that current. Energy is a function of the inrush current, the input voltage and time.
Pulse resistor selection depends on the pulse condition, its peak, duration and energy. Determining the main elements of the pulse is the major challenge when choosing the resistor. The electric motor supply lines could be affected by several external events, resulting in many potential pulse conditions.
Resistors in AC and DC motor control applications can be in the main motor supply lines or low voltage control circuits. Those in supply lines are always on, so the steady state conditions of the motor must be known. They must also be able to survive pulse or surge events.
As current sense resistors are used in measurement applications tolerance and stability are more of an issue than power handling capability. Temperature coefficient of resistance and the resistor value are also important considerations.
