Feature: 1. Brushless Motor ESC: This electric speed controller is used for brushless motor, with continuous current of 30A, instant current of 35A, 40A for 10 seconds. 2. Upper Speed Limit: The speed is up to 300,000rpm for 2 pole internal rotation, 50,000rpm for 12 pole external rotation, and 42,000rpm for 14 pole external rotation. 3. PWM Control: The ESC is controlled by 8KHz PWM, using the speed control curve, auto throttle adaptation, suitable for more remote control devices. 4. Stable and Reliable: The ESC uses BEC, MCU separates the power supply, and the work is more stable. With multi protections, safer and more reliable. 5. Wide Applications: Widely used in machinery industry, automobile industry, construction industry, railway, electronics industry, power plants, etc. Specification: Item Type: Brushless Motor ESC Material: PCB Basic Parameters: Voltage Range: 4-16V Number of Batteries: 4-12NIMH 2-3LIPO (4LIPO does not allow BEC output) BEC Output: Continuous 2A (instant 3A) 2LIPO 4-5 Micro Servo 3LIPO 3-4 Micro Servo.
