PI Closed Loop Control Of Brushless Dc Motor With Over Temperature Protection

48V brushelss dc motor speed driver, BLDC motor controller for 3 phase bldc motor with hall sensors

Features:

♦ Surface-mount technology and small size.

♦ 2-Quadrant PI close-loop control of speed with good linearity.

♦ Variable Parameter setting for different motors

♦ Control functions of F/R, enable, brake, speed reference and out put functions of speed pulse(PG), alarm. Over temperature protection.

♦ Three kinds of reference inputs: analog voltage, PWM, frequency.

♦ Suitable for 3 phase brushless DC motor with hall sensors

♦ Use of industrial grade chips.

Description:

N Serires is speed driver with variable parameters and PI close-loop. The reference can be0∼5V analog voltage or 0∼100%PWM. Also it can be 0∼3kHz frequency by adding a F-V unit on PCB. Parameters can be set by DIP switches and potentiometers such as pole number, max speed, ramp time, loop filter time and peak current etc. Votage grades are 12,24,36,48VDC. Working current grades are 5,10,15A. Ambient temperarure grade are -10∼+45ºC,-40∼+65ºC

Naming Rule:

     BLSD 48 30 DC – 2Q – N - T  P
BLSD:         BLDC speed driver

     48:         Rated Voltage (VDC)

     20:         Peak Current Limit(A)

    DC:         DC power input

    2Q:         2-Quadrant driving mode

      N:         N series (normal size and variable parameters)

      T:         T=-40~+65 ºC Ta, unlabelled=-10~+45 ºC Ta

      P:         P=0-3KHz pulse input at SV,unlabelled= 0-5V at SV
