JYQD_V6 Overview

Part: JY61P — Not specified (likely a generic BLDC driver board)

Type: BLDC Motor Driver Board (based on context, not a single IC)

Description: A driver board designed for three-phase brushless DC (BLDC) motors, utilizing external Hall sensors or sensorless back-EMF detection, and controlled by an STM32F401RE microcontroller via external MOSFET drivers (JY21L) and a comparator IC (LM339N).

Operating Conditions:

  • Supply voltage: 3V and more (for some boards), 5V and more (for some boards), 11V and more (for some boards)

Absolute Maximum Ratings:

Key Specs:

  • Control method: Hall sensor based or sensorless (back-EMF)
  • Motor type: Three-phase BLDC (e.g., CDROM, HDD motors)
  • Driver ICs: 3x JY21L high speed power MOSFET drivers
  • Comparator IC: LM339N (external)
  • Control signals: 6 MOSFET drive signals (3 PWM, 3 GPIO)
  • Hall sensor input: 3 differential comparator signals
  • PWM frequency: Configurable via Timer 3 (Period = 10000, Prescaler = 1 or 2)
  • UART Baud Rate: 115200

Features:

  • Supports both Hall sensor and sensorless control methods
  • Utilizes external LM339N for Hall sensor signal conditioning or back-EMF zero-crossing detection
  • Drives 6 MOSFETs via 3 JY21L driver ICs
  • Compatible with STM32 NUCLEO-F401RE prototype board
  • Software developed with SW4STM32 and STM32CubeMX
  • External interrupt handling for Hall sensor signals (rising/falling edge)
  • Adjustable PWM for motor speed control

Applications:

  • Three-phase BLDC motor control
  • CDROM motor control
  • HDD motor control

Package:

  • Not applicable (this describes a board, not a single IC package)

JYQD_V6 Applications

Since BEMF based on induction and induction needs motion we cannot expect, that the motor starts without any push.

In the following we see some other motors we used together with the same program.

The first one is a hard drive motor and we used this device to conduct an experiment to show the power of an angular momentum.

And here are two different floppy drive motors. A relatively small impulse starts both immediately.
