30V 50A Brushless DC Motor Phidget
This controller can deliver up to 50A of continuous current and 75A of peak current to a single brushless DC motor.
The 30V 50A Brushless DC Motor Phidget is a high-performance brushless DC motor driver. It has an 8-30V DC supply input, and provides up to 50 amps of continuous current, with a peak current capacity of 75 amps to a single brushless DC motor. The motor must have Hall-effect feedback for this controller to function.
This controller includes three operating modes: BLDC Motor, Position Controller, and Velocity Controller. The Position and Velocity Controller modes utilize the built-in encoder channel or Hall-effect sensor data to deliver fast and precise closed-loop control. Prebuilt tuning software is available through the Phidget Control Panel on Windows. In BLDC Motor mode, the motor can be manually controlled, allowing for custom control loops. Comprehensive guides are available for each mode.
There are several built-in safety features, including an E-Stop circuit, thermal protection, over-current protection, advanced failsafe modes, supply voltage monitoring, and polarity protection. For detailed information about these features, refer to the API.
Additional features include regenerative braking, surge current limiting, automatic inductance measurement, electrical isolation, and more.
The 30V 50A BLDC Motor Phidget must be connected to a VINT Hub Phidget to function. A Power Guard Phidget is also required for most applications. For more information, review our Power Guard Guide.
