Product overview
The cysmodel CYS-S9257D provides servo actuation for model cars and helicopters. Its physical configuration combines a coreless motor, metal gears, dual bearings and a 25T output spline, with a 250mm connection lead. Nominal mass is 28g, with a separate weight specification of 28g±0.1g. Integration dimensions have conflicting width values: 36*15.2*28.8mm and 36*25*28.8mm. This dimensional discrepancy leaves the required installation width unresolved. The hardware is a digital servo component for integration into a model.
Electrical integration uses a 4.8-6.0V supply and PWM control with a 1500usec neutral position. Travel is 90° overall, or 45° to either side, with reverse operation over a 1000usec ~ 2000 usec pulse range and a 2usec deadband. At 4.8V, no-load speed is 0.10sec/60° and torque is 2.2kg.cm; at 6.0V, these become 0.08sec/60° and 2.5kg.cm. Standby/no-load current is respectively 10mA/120mA and 10mA/150mA. Stall current is listed as 800mA/900mA without a voltage assignment, while the temperature range is (-)10 to +50 °.
