Motor Control Functions

PWM Speed Control

The JYQD-VH8500 supports PWM-based speed adjustment with a PWM frequency range of 10–20kHz and a duty-cycle range of 0–100%.

This allows the controller to be integrated into control systems where motor speed is regulated through a PWM control signal.

0–5V Analog Speed Regulation

The controller also supports 0–5V analog voltage speed regulation, providing an alternative interface for applications that use an analog voltage signal for motor speed control.

Enable Control

The integrated Enable function allows the controller to be incorporated into systems requiring an external motor enable/disable control signal.

Reversing Function

The JYQD-VH8500 provides a reversing function, allowing the motor control system to support forward and reverse operation where the motor and application requirements are compatible.

Speed Signal Output

A speed signal output function is provided for applications that require motor speed information to be transferred to an external control or monitoring system.

Protection Functions

The JYQD-VH8500 incorporates multiple protection functions designed to improve controller and motor system reliability.

The available protection functions include:

• Overload protection
• Abnormal current protection
• Locked-rotor protection
• Soft switching
• Over-temperature protection
• Over-voltage / under-voltage protection

These functions help provide additional protection for the BLDC motor control system during abnormal operating conditions.

Operating Environment

The JYQD-VH8500 is specified for an operating temperature range of -40°C to +85°C and an operating humidity of ≤90%.

These specifications make the controller suitable for a wide range of industrial and equipment-control environments, subject to the complete system design and application conditions.

Compact Controller Design

The controller dimensions are:

152mm * 97mm * 74.5mm

Its compact form factor allows it to be integrated into equipment where installation space is limited.

Applications

The JYQD-VH8500 can be considered for applications requiring high-voltage sensorless BLDC motor control, including:

• High-voltage BLDC motor systems
• Brushless DC motor equipment
• Industrial motor control equipment
• Motor-driven equipment
• OEM motor control systems
• Equipment requiring PWM speed control
• Equipment requiring 0–5V analog speed regulation
• Motor systems requiring reversing and enable control

Actual application suitability should be evaluated according to the motor specifications, operating conditions, mechanical load, and complete system requirements.

Why Choose JUYI Tech for BLDC Motor Control?

JUYI Tech focuses on BLDC motor driver technology and provides BLDC motor controller solutions for different motor-control requirements.

In addition to standard BLDC motor driver products, JUYI Tech supports OEM and ODM customization for projects requiring specific electrical, mechanical, control, or interface requirements.

For applications where a standard controller does not fully match the motor or system requirements, customers can provide the motor specifications, operating conditions, load requirements, speed range, voltage, current, and control requirements for technical evaluation.

Product Selection and Technical Support

Selecting the correct BLDC motor controller requires more than matching the motor's nominal voltage and current. Motor characteristics, startup requirements, operating speed, mechanical load, control method, and working environment should also be considered.
