Description
The Basic ESC 500 is a high-power electronic speed controller (ESC) for three-phase brushless motor like Blue Robotics’ thrusters and motors. It has a 50A current rating suitable for both the T200 and T500 Thrusters and is suited to operate in poorly cooled installations, such as in an ROV enclosure.
Key Features
- Simple, robust brushless electronic speed controller
- Compact form factor
- Forward/reverse rotation direction for forward/reverse thrust
- High-efficiency, low-heat design optimized for minimal cooling environments
It comes in two versions: a standard version and BlueBoat version. The standard version has a male XT90 power connector and female 4mm bullet connectors to the thruster. It also includes a set of male 4mm bullet connectors to install on the thruster. The BlueBoat version comes with spade connectors for power and an MT60 connector for the motor. The BlueBoat version also includes a 5V 5A power supply to power other electronics.
To get started quickly with your thruster and ESC, we recommend the Thruster Commander, which provides the appropriate control signal and is easy to get started with!
