Cytron Technologies has just launched the new driver for DC Brushless Motor, the BLD04A
Description: BLD04A is designed to drive the Linix 10W and 30W brushless dc (BLDC) motor. It offers several enhancements over the original Linix BLDC motor driver such as closed loop speed control, UART interface and better protection for both the motor as well as the driver. Besides that, the interface of BLD04A is compatible with the original Linix BLDC motor driver and this makes the upgrading for existing users an effortless process.
• Powered by high performance dsPIC Digital Signal Controller.
• Operating at DC +24V ±15%.
• Support up to 4A per phase.
• 4-Quadrant control.
• 5V logic level input for Start/Stop, Run/Brake, Direction and Alarm Reset.
• Support analog voltage (0 – 5V) or PWM signal for speed control.
• Support UART interface.
• Selectable open loop or closed loop speed control.
• Current limiter.
• 12 pulses per revolution encoder output.
• Alarm indicator for overvoltage, undervoltage, out-of-phase and overload alarm.
• Comes with casing for better durability and easier mounting.
• Support the following Linix BLDC motor:
What is so special about this driver? Well, it has feedback control, so when your robot go up hill, it will try to maintain the speed; same apply for going down hill. Having similar pin with Vexta motor, it is fully compatible for IFC-BL02 and AR40B. Of course it can also be intefaced with your own board. The User’s Manual do show this in details, please refer to User’s Manual before you do anything.
It can also be interface with microcontroller through UART, here is the setup (of course, it is also being ilustrated in User’s Manual in detail). The figure shows interface between BLD04A with SK40C through UART. Sample source code is also provided.
Another great feature, it can be controlled from computer through UC00A, a GUI is provided for user to have speed feedback.
You can control the speed, direction, brake, run, stop. What more can you ask?
