CROUZET controller Germany CROUZET model CROUZET price

CROUZET controller is the core control device used to control the start, operation, advance/retreat, speed, stop, and other electronic components of electric vehicle motors. It is like the brain of the electric vehicle and 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, with considerable control effect, improving the universal adaptability of electric vehicle controllers, so that electric vehicle motors and controllers no longer need matching.

CROUZET 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 balance 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, it has inherent defects, mainly including: 1) At least one complete code disk pulse must be detected within the speed measurement cycle, limiting the minimum measurable speed; 2) The 2 control system timer switches used for speed measurement are difficult to keep strictly synchronized, making it impossible to guarantee speed measurement accuracy in occasions with large speed changes. Therefore, traditional speed loop design schemes applying this speed measurement method find it difficult to improve the speed following and control performance of servo drives.

CROUZET 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 performed. After one work cycle ends, it automatically enters the next work cycle. Some PLC also have dedicated step control instructions, making step control more convenient.

CROUZET controller data communication

Most PLC have varying degrees of data processing capabilities [3], such as the F2 series, C series, S7 series PLC, etc., capable of performing 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, and voltage. In the past, PLC was used for logic control, and the control of these physical quantities mainly relied on instrument control or Distributed Control 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.
