The RS-395L motor developed by Kinmore Motor can be applied in automotive power lumbar support systems. This motor controls the inflation and deflation of the built-in airbag inside the lumbar support, helping provide effective lower back support and enhancing driving comfort. Kinmore Motor offers motor solutions for automotive power lumbar support applications, focusing on optimizing motor structure and performance to achieve higher operating efficiency and deliver better customized products for customers. Below, let’s take a look at how Kinmore Motor provides power solutions for automotive power lumbar support systems.
The core of a car’s electric lumbar support’s operation lies in its built-in motor drive control. In short, when in use, a light touch of a finger activates a switch mounted on the seat or console, activating a pneumatic motor to inflate an airbag concealed within the seat. This provides precise, additional lumbar support, reducing back pain while driving. Kinmore uses the RS-395L motor in its car electric lumbar support; this extended 395L motor was specifically developed for this application.
The structural and performance characteristics of the Kinmore RS-395L motor can be summarized as follows:
- Built-in varistor, capacitor, and inductor stabilize the internal current path, reducing noise and electromagnetic interference while preventing excessive electromagnetic radiation;
- A PTC temperature-controlled thermistor increases its resistance when the temperature reaches a certain value, protecting the motor;
- A protective magnetic ring is added to the motor housing to enhance the stator magnetic field strength; the output shaft features a concave ring and knurling for easier final connection and to increase the friction coefficient of the connecting components.
In addition, this motor is 55.1mm ± 0.15mm long, equipped with a dedicated direct-plug connector at the tail for easy customer installation, and the axial travel is controlled by a single screw in the shaft center of the rear cover. The overall length is 77mm ± 0.5mm, rated voltage is DC13.5V, rated load torque is 338g.cm, speed is 4420rpm, load current is approximately 1.8A, and output shaft length is 44.5mm ± 0.3mm. This motor can be customized according to customer needs. With optimized structural design, it has stable performance, significantly improved energy efficiency, effectively extended working time and operating cycle, and improved the service life of the entire machine.
Kinmore Motor currently customizes and manufactures a variety of motors to meet market demands, all of which can be widely used in the automotive parts industry. This RS-395L model motor, in addition to its applications in automotive electric lumbar supports, can also be used in vacuum cleaners, small hair dryers, electric drills, hardness testing machines, and its structure and performance are optimized to provide the best power solutions for these applications.
For many years, Kinmore Motor has been deeply involved in the research and development and production of automotive parts. Currently, its main applications in the automotive parts field include: the RS-557SH motor, which boasts an ultra-long service life, high torque, and high load capacity, suitable for EPB electronic parking brake systems; the FT-280A motor, with low cogging torque, fast response speed, and built-in PTC, suitable for automotive door locks; and the RF-370 motor, featuring a metal back cover and oil-immersed bearings, offering stable performance and low noise (<30dB), suitable for automotive air conditioning baffles.
Kinmore Motor adheres to a meticulous R&D approach, continuously optimizing motor solutions for automotive parts applications through innovation. Building upon existing structures, they design motor solutions with higher performance, lower noise, lower cost, and easier mass production based on customer needs.
