Product overview
The cysmodel CYS-S3210 Coreless Digital Servo is an actuator for model control applications, including 500–550 helicopter rudder/tail control, 1/12 racing cars and fixed-wing Jet/CAP models. Its all-metal construction combines a coreless motor, metal gears, dual bearings and a 25T output spline. Integration provisions include a 250mm lead and PWM control with a 1500usec neutral position. Travel is 90° overall, with 45° to either side, and the operating direction is reverse over a 1000usec ~ 2000 usec pulse range.
Electrical operation spans 6.0 ~7.4Volts and temperatures from (-)20 to +60 degree C. At 6.0V, torque is 5 kg.cm and no-load speed is 0.04sec/60°; at 7.4V, these become 6 kg.cm and 0.03sec/60°. Physical specifications include conflicting dimensions of 35*15*32.8mm and 35*15*29.5mm, and weights of 45g and 43g±1g. Additional torque and speed specifications are 4.0Kg.cm ~ 5.0Kg.cm and 0.05sec ~ 0.04sec/60 °, without voltage assignments. These differences leave the installation envelope, mass and performance specification unresolved.
