Product Overview

Technical Data

The BLDC series brushless DC motors and drivers are newly launched products, developed for low-power motor drive applications.

With the rapid advancement of electronic technology, manufacturing processes and performance of electronic products are continuously upgraded. Adopting large-scale hardware integrated circuits, this product features strong anti-interference capability and fast dynamic response. Compared with conventional DC motors, it delivers outstanding control performance with maintenance-free operation, long service life and constant torque output.

It can drive any low-voltage three-phase brushless DC motor with peak current below 15A and supply voltage within 50V. Widely applied in knitting machinery, medical equipment, food processing machinery, power tools, garden machinery and various electrical automation control systems.

Features

• Adopts pure SPWM sinusoidal pulse width modulation technology with dual closed-loop control of current and speed, delivering high low-speed torque and smooth operation.

• Stable torque output at high speed; maximum rotational speed up to 8000 r/min.

• Wide speed regulation ratio up to 1:75. When matched with 4-pole BLDC motors, the minimum speed reaches 60 r/min. Wider speed range is available for motors with more poles.

• Flexible Hall magnetic pole position configuration; selectable electrical angles: 60°/300°/120°/240°, compatible with various motor specifications.

• Two speed control modes: onboard potentiometer adjustment & analog signal input terminal for flexible user operation.

• Opto-isolated input signals for start/stop, rapid braking and forward/reverse rotation switching.

• Opto-isolated open-collector (OC) output signals for speed feedback and fault alarm.

• Integrated protection & alarm functions against overcurrent, overvoltage, locked rotor and motor loss of control.
