HELU controller, German HELU model, HELU price

The HELU controller is the core control device used to manage the start-up, operation, forward/reverse movement, speed, and stopping of electric vehicle motors, as well as other electronic components of the electric vehicle. It acts as the brain of the electric vehicle and is a critical component. Electric vehicles mainly include electric bicycles, electric two-wheel motorcycles, electric tricycles, electric three-wheel motorcycles, electric four-wheelers, and battery-powered vehicles. Electric vehicle controllers have different performance characteristics depending on the vehicle type. Ultra-quiet design technology: unique current control algorithms suitable for any brushless electric vehicle motor, providing effective control results, improving the general adaptability of the electric vehicle controller, and eliminating the need for matching between the electric vehicle motor and the controller.

HELU 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, with the corresponding common speed measurement method being the M/T method. Although the M/T method offers certain measurement accuracy and a wide measurement range, it has inherent drawbacks, including: 1) At least one complete code disk pulse must be detected within the speed measurement period, 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 scenarios with significant speed changes. Therefore, traditional speed loop designs using this method struggle to improve the speed following and control performance of servo drives.

HELU Controller Functions

1) Counting Control: The PLC provides users with counters categorized into standard counters, reversible counters (up/down counters), and high-speed counters, used to execute counting control commands for various purposes. When the counter value equals the set value or falls within a specified range, a control command is issued. The counter value can be read during operation and modified while running. 2) Step Control: The controller provides a certain number of shift registers, allowing convenient implementation of step control functions. Upon completion of one process step, the next step proceeds automatically. After one work cycle ends, the next work cycle begins automatically. Some PLC units also feature dedicated step control instructions, making step control more convenient.

HELU Controller Data Communication

Most PLC units possess varying degrees of data processing capabilities [3], such as the F2 series, C series, and S7 series PLC, capable of performing data operations like addition, subtraction, multiplication, division, exponentiation, and square roots; logical operations like word AND, word OR, word XOR, and inversion; as well as shifting, data comparison, and value conversion. In process control or closed-loop control systems, there are continuously changing physical quantities such as temperature, pressure, flow rate, speed/displacement, current, and voltage. Previously, PLC was used for logic control, while control of these physical quantities relied mainly on instrument control or Distributed Control Systems (DCS). Large and medium-sized PLC units have physical quantity processing functions, and many small PLC units also possess this capability, making programming and use convenient. Most PLC units have communication capabilities, enabling communication between PLC and computers, as well as between PLC and PLC. Through these communication technologies, PLC can more easily form Factory Automation (FA) systems. They can also connect to external devices such as printers and monitors to record and monitor relevant data.
