Excellent heat dissipation performance: The aluminum shell brake resistor uses an aluminum shell as the
shell material. Aluminum has good thermal conductivity and can
quickly dissipate the heat generated by the resistor, ensuring the
stability of the resistor during high-power operation.
Sturdy and durable structure: The aluminum shell brake resistor is designed with a sturdy
structure, capable of withstanding mechanical vibration and shock.
Its aluminum shell material not only provides excellent heat
dissipation performance, but also enhances the mechanical strength
of the resistor and prolongs its service life.
Easy to install and maintain: The aluminum shell brake resistor has a simple structure, is
convenient to install and has a low maintenance cost. Its
standardized external dimensions and installation holes enable it
to be conveniently integrated into various devices.
Application scenarios
Frequency converter:In the frequency converter, the aluminum shell braking resistor is
used during the deceleration and braking process of the motor to
consume the regenerative energy generated by the motor, ensuring
the stable operation of the frequency converter.
Servo system: In a servo system, aluminum housing braking resistors are used to
regulate the motor's speed and torque, ensuring precise control of
the servo system.
In the rectifier, the aluminum shell braking resistor is used to
regulate the current and voltage to ensure the normal operation of
the rectifier.
Inverter: In the inverter, the aluminum shell braking resistor is used for
current sampling and voltage feedback, ensuring the stability and
efficiency of the inverter.
Rectifier: In the rectifier, the aluminum shell braking resistor is used to
regulate the current and voltage to ensure the normal operation of
the rectifier.
