Berghof controller Germany Berghof model Berghof price

Berghof controller is the core control device used to control the start, operation, forward/reverse movement, speed, and stop of electric vehicle motors, as well as other electronic components of electric vehicles. It is like the brain of the electric vehicle and is an important component. Electric vehicles mainly include electric bicycles, electric two-wheel motorcycles, electric tricycles, electric three-wheel motorcycles, electric four-wheel vehicles, battery-powered vehicles, etc. Electric vehicle controllers have different performance and characteristics due to different vehicle models. Ultra-quiet design technology: unique current control algorithm, suitable for any brushless electric vehicle motor, and has considerable control effect, improving the universal adaptability of electric vehicle controllers, so that electric vehicle motors and controllers no longer need matching.

Berghof controller introduction

In the speed closed loop of servo drives, the real-time speed measurement accuracy of the motor rotor is crucial for improving the dynamic and static characteristics of speed control in the speed loop. To seek a balance between measurement accuracy and system cost, incremental optical encoders are generally used as speed sensors, and the corresponding common speed measurement method is the M/T speed measurement method. Although the M/T speed measurement method has certain measurement accuracy and a wide measurement range, this method has its inherent defects, mainly including: 1) At least one complete code disk pulse must be detected within the speed measurement cycle, which limits the minimum measurable speed; 2) The 2 control system timer switches used for speed measurement are difficult to keep strictly synchronized, and speed measurement accuracy cannot be guaranteed in measurement occasions with large speed changes. Therefore, traditional speed loop design schemes applying this speed measurement method are difficult to improve the speed following and control performance of servo drives.

Berghof controller functions

1) Counting control: The counters provided to users by PLC are divided into ordinary counters, reversible counters (up/down counters), high-speed counters, etc., used to complete counting control commands for different purposes. When the counter value equals the counter set value, or is within a certain numerical range, a control command is issued. The count value of the counter can be read during operation, and can also be modified during operation. 2) Step control: The controller provides users with a certain number of shift registers, which can conveniently complete step control functions. After one process is completed, the next process is automatically carried out. After one work cycle ends, it automatically enters the next work cycle. Some PLC also have special step control instructions, making step control more convenient.

Berghof controller data communication

Most PLC have varying degrees of data processing capabilities [3], such as F2 series, C series, S7 series PLC, etc., which can complete data operations such as addition, subtraction, multiplication, division, exponentiation, square root, etc., logical operations such as word AND, word OR, word XOR, inversion, etc., shifting, data comparison, and conversion of transmitted values. In process control or closed-loop control systems, there are continuously changing physical quantities such as temperature, pressure, flow, speed/displacement, current, voltage, etc. In the past, PLC was used for logical control, and the control of these physical quantities mainly relied on instrument control or distributed systems DCS. Large and medium-sized PLC have physical quantity processing functions, and many small PLC also have physical quantity processing functions, making programming and use very convenient. Most PLC have communication capabilities, enabling communication between PLC and computers, and between PLC and PLC. Through these communication technologies, it is easier for PLC to constitute factory automation (FA) systems. They can also be connected to external devices such as printers and monitors to record and monitor relevant data.
