Product overview
The cysmodel CYS BLS5815 is a digital brushless servo intended for 700 helicopter swashplate control and fixed-wing aircraft applications. Its physical construction combines an all-metal housing, titanium gears and dual bearings, with a 25T output spline for the mechanical connection. The servo weighs 77±1g and has specified dimensions of 40*20*39.35mm; its shorter descriptive dimensions are 40*20*39mm. A 300mm lead provides the electrical connection, with brown/black identifying negative, red positive and orange/white the signal conductor.
Integration requires a 6.0-7.4V supply and PWM control with a 1500usec neutral position. Reverse operation is specified over 1000usec ~ 2000 usec, with 90° total travel and 45° to each side. At 6.0V, torque is 13kg.cm and no-load speed is 0.08sec/60°; at 7.4V, these become 15kg.cm and 0.07sec/60°. Standby/no-load current is respectively 20mA/80mA and 20mA/100mA at those voltages. Additional integration parameters include a 2usec deadband, 3.0A/3.5A stall current and a temperature range of (-)10 to +50 °.
