Product overview
The Flash Hobby FH-1720MG Micro Servo combines a coreless motor with programmable digital control and a directly driven potentiometer. Its construction includes high-precision Taiwan-made aluminium gears with hard anodizing, dual ball bearings and a nylon-plus-fiber case. The servo measures 28 × 13.2 × 29.6 mm and operates on DC4.8–6.0 V at temperatures from -10°C to +50°C. Electrical connection uses a JR connector and 28awg PVC wiring, with brown for negative and red for positive.
Pulse width modulation control uses 1520 μsec, with a working frequency specification of 1520μs / 330hz and a dead band of 7μs. Operating travel is 120° ± 10°, the limit angle is 180° ± 10°, and pulse travel spans 800→2200 μsec. At a test voltage of 4.8V, idle current is 90±20mA and running current is 750±50mA. At 6.0V, these currents are 100±30mA and 950±50mA respectively. The electronics incorporate an IC drive and a digital control amplifier.
