In-Depth Applications for this High Voltage BLDC Motor Driver
The BLSD-HV Series is a high voltage BLDC motor driver designed for machinery that operates directly from a 110V or 220V AC wall outlet, eliminating the need for a large external DC power supply. Its “HV” (High Voltage) and “ADC” (AC/DC input) capabilities make it a powerful and efficient solution. Key application areas include:
- Industrial Machinery: Ideal for construction spraying machines, PCB board cutting machines, and textile equipment that require high, continuous power from an AC source.
- Automation & Conveying: This high voltage BLDC motor driver can drive large conveyor systems and sorting machines that require high torque at high voltage.
- Pumps & Ventilation: Operates large-scale industrial fans, blowers, and pumps efficiently, running directly from the AC main supply using this high voltage BLDC motor driver.
Control Interface and Features
1. Power Supply Port:
A wide range AC or DC power supply of AC45-275V/50-60Hz in single phase, DC60-385V can be used for the driver. The PE point of driver and power supply system must be connected reliably for safety. Please take attention to the high voltage warning.
2. Motor Windings Port:
Connect three phases of windings to the U/V/W points in correct sequence. PE on motor case must be connected to PE point of this port for safety. Please take attention to the high voltage warning.
3. Motor Hall Sensor Port:
Connect Hall sensors Hu/Hv/Hw to the port in correct sequence. This port is insulated from inside circuit by optocoupler and Vc supply is provided by driver.
4. Control Signal Port:
This port is insulated from inside circuit by optocoupler and one line isolated 12V power supply is provided by driver for external use, the current is less than 50mA
F/R: Rotating direction control. Forward=open ,Reverse=connect to SGND
The driver can provide safety forward/reverse control. If the direction is changed suddenly when the motor is running, the motor will cut down the power and sliding to zero speed smoothly and then change rotating direction in order to avoid the shock impact. At the moment that the driver power up, if the speed is not zero, then it will start until the speed is zero.
EN: Enable control function. Enable when optocoupler conduct. The driver can only be work when enable. The alarm can be reset by EN=disable once
SV：Analog reference voltage input of 0~10V. Input impedance 200K. It is insulated from inside circuit by a linear optocoupler.
SVP：Digital reference pulse input of 0~3KHz frequency or 0~100% PWM@50-1KHz .
PG：Speed pulse output in OC（30Vmax/5mA）. This signal can be made in synchronize to one phase hall sensor signal or 6 times frequency multiplier. The motor speed is in proportion to the frequency. Motor speed（rpm）=PG frequency（Hz）x120/N. N is the pole number of motor. Or, motor speed（rpm）=PG frequency（Hz）x120/N/6 (6 times frequency multiplier).
AL：Alarm output in OC（30Vmax/5mA）. The driver has self-diagnostic function. When the following conditions come, the alarm comes up, and optocoupler will conduct.
For items of NO.1~5, green LED P/A will be blinking. The alarm can be reset by EN=disable once.
For items of NO.6~7, red LED will brighten. The alarm can be reset only you Off-on supply again.

Frequently Asked Questions (FAQ)
Q: What is the main benefit of the “High Voltage” (HV-Series)?
A: The “HV-Series” is an industrial-grade high voltage BLDC motor driver. Its key benefit is the AC/DC dual-purpose input. It can be connected directly to a 110VAC or 220VAC power source (or high voltage DC), allowing it to drive powerful motors (up to 24A) without a separate, large DC power supply, which saves cost and space.
Q: What does “PI Closed-Loop” control mean for this driver?
A: This high voltage BLDC motor driver uses a PI (Proportional-Integral) algorithm for its speed or current control. It reads the Hall sensor feedback (PG output) and compares it to the set speed (SV), then automatically adjusts the power to maintain that speed, even if the load changes.
Q: How do I control the speed of this BLDC motor controller?
A: This BLSD-HV high voltage BLDC motor driver is highly flexible. You can control the speed using a 0-10V analog signal (at SV), a PWM pulse signal, or a 0-3KHz pulse frequency signal (at SVP), selectable via DIP switch.
Q: What safety features does this bldc motor drive include?
A: This high voltage BLDC motor driver is built for safety. It includes reliable protections for incorrect Hall signals, low/over voltage (LV/OV), over-temperature (OT), over-load (OL), and short-circuit (SC), with alarm (AL) and LED indicators for diagnostics.
