rzb zimmermann electrical components consist of two conductors placed close to each other with a non-conductive insulating dielectric layer in between, forming a capacitor. When voltage is applied across the two plates of the capacitor, it stores electric charge. The capacitance value is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates. The basic unit of capacitance is the Farad (F). In circuit diagrams, the letter C is commonly used to represent capacitive elements; capacitors are components that store electric charge and electrical energy (electric potential energy). A system of conductors where one conductor is enclosed by another, or where all electric field lines originating from one conductor terminate on another conductor, is called a capacitor.

rzb zimmermann electrical component functions

The starter solenoid switch is a key component of the starter motor, and its design quality directly affects the reliability of the starter. The starter solenoid switch has two main functions: first, to connect the main circuit to rotate the starter motor; second, to push the drive gear out via the shift fork to engage with the engine flywheel ring gear. Therefore, the solenoid switch is required to have appropriate attraction force, appropriate stroke, and contacts capable of reliably switching high currents. Additionally, it is required to minimize volume and weight as much as possible. Based on these characteristics, the contact structure of solenoid switches generally adopts a contact form, i.e., the moving contact is made into a bridge shape or disc shape to provide a larger heat dissipation surface and thermal capacity. The magnetic system mostly adopts a solenoid electromagnet structure to meet the requirements of appropriate stroke, appropriate attraction force, small volume, and light weight. The moving iron core of the solenoid switch can move smoothly within a brass bushing equipped with a solenoid coil. The moving iron core pull rod is connected to the shift fork and one-way clutch. Under the action of the return spring, the moving iron core remains in the initial non-operating position. During starting, the starter drive gear needs to move forward by approximately 12-27mm. Therefore, when the solenoid switch begins to engage, a large magnetomotive force is required to generate the necessary initial attraction force. After engagement, the air gap decreases, and the electromagnetic attraction force increases sharply, greatly exceeding the force required to maintain the engaged state. For this reason, the solenoid switch uses two coils (pull-in coil and hold-in coil). Initially, both the pull-in coil and hold-in coil jointly generate electromagnetic attraction. After the switch contacts engage, the pull-in coil automatically disengages from operation, and only the hold-in coil maintains the switch in the engaged state. The hold-in coil current is relatively small, allowing it to be wound with thinner wire. This reduces the volume of the solenoid switch while achieving reasonable attraction force matching. To ensure the reliability of the starter motor, emphasis must be placed on controlling the design quality of the solenoid switch.

1. Wiring harnesses are designed to facilitate installation and maintenance, ensuring that electrical equipment can operate under the harshest conditions. Wires of different specifications and colors used for various electrical equipment in the vehicle are reasonably arranged and bundled together with insulating material, making them complete and reliable. 2. Normal selection of wire cross-sectional area and color codes: (1) Correct selection of wire cross-sectional area: Electrical equipment in the vehicle selects the wire cross-sectional area based on the magnitude of the load current. For electrical equipment operating for long durations, wires with an actual current carrying capacity of 60% can be selected; for electrical equipment operating for short durations, wires with an actual current carrying capacity of 60%-104% can be used. (2) Selection of wire color codes: To facilitate identification and maintenance, wires in the harness use different colors. For easy labeling in circuit diagrams, wire colors are represented by letters, with the corresponding colors noted in each circuit diagram.

rzb zimmermann electrical component characteristics

Dynamic characteristics refer to the output behavior of a sensor when the input changes. In practical applications, the dynamic characteristics of sensors are often expressed by their response to certain standard input signals. This is because the response to standard input signals can be easily obtained through experimental methods, and there is a certain relationship between the response to standard input signals and the response to arbitrary input signals; often, knowing the former allows inference of the latter. The most commonly used standard input signals are step signals and sinusoidal signals, so the dynamic characteristics of sensors are also commonly expressed by step response and frequency response.
