Overview of FOC driver principle
This driver utilizes FOC to achieve current vector control and electromechanical stator magnetic field vector control
Small torque ripple, high efficiency, low noise, and fast dynamic response. Distinctive in control principle, brushless
The electronic speed controller (ESC) can only control the motor to operate at high speeds and cannot control it at low speeds; whereas the Field-Oriented Control (FOC) controller can fully control the motor
There is no such limitation, and precise control can be achieved at any speed
Support multiple adjustments such as duty cycle speed regulation, torque control, speed closed-loop control, position closed-loop control, and angle control
Rapid method
Supports constant speed, constant torque (constant current), and constant power output
Supports multiple input signals including potentiometer, analog signal, PPM, RS485, CAN, and CANopen
The potentiometer, analog signal, and PPM can learn the mapping range through the host computer. They can adapt to different resistance values and different
Time (duty cycle) signal:
485, CAN, CANopen communication isolation; support 485, CAN, CANopen multi-station communication
Facilitate communication control with multiple controllers (such as PLC)
The PID parameters of motor current are automatically tuned, and the speed PID and position PID can be configured on the host computer
The maximum starting/load current and braking (brake) current can be configured separately
Supports internal temperature monitoring of the drive, with configurable overheat protection temperature
Supports driver power supply voltage monitoring, with configurable overvoltage/undervoltage shutdown monitoring values:
Supports current doubling output, capable of delivering high torque during startup and under heavy load conditions
The motor can output with locked-rotor for a long time under constant power or constant torque conditions:
Intelligent learning of new motors, allowing quick adaptation to new motors
Display motor speed, position, temperature, and other information in real time:
The host computer is equipped with limit switches. It can be flexibly configured according to the application scenario
Supports motor speed measurement and motor locked-rotor detection/locked-rotor limit stall:
With a PWM frequency of 25kHz, the motor speed regulation is quieter without PWM
All interfaces are ESD protected, adaptable to complex on-site environments
Using the ARM Cortex-M4@168MHz processor, computation is not limited
