FT5320M uses a combination of copper and aluminum gears, and the gear shaft is thickened to 2.0. Optimized center distance, double ball bearing design, longer life. Automatically enter protection after 8 seconds of stalling. 70 overheat protection With 8-second overload protection and 70 overheat protection After the servo is stalled, the output torque exceeds the overload torque and continues for more than 8 seconds, and then automatically outputs the protection torque. (Overload torque, protection time, protection torque support modification) With waterproof characteristics Aluminum middle shell design for better heat dissipation Position sensor can rotate 180 Appearance size: 40x20x43mm Unlimited: Mechanism limit angle Output shaft: 25T or 5.9mm Gear material: Copper teeth Bearing type: Ball bearing Motor type: Core Motor Working voltage: 6V 7.4V No-load speed: 0.185sec or 60 0.151sec or 60 No-load current: 100mA 120mA Stalled torque: 16.5Kg.cm 20Kg.cm Stalled current: 2.3A 3A Rated load: 5.5Kg.cm 6.5Kg.cm Rated current: 800mA 1000mA Voltage range: 4V-8.4V Kt constant: 6.5Kg.cm or A Control signal: PWM Control system type: Digital comparator Operation angle 180 Pulse width range 5002500 sec Electronic protection: 8 seconds of stall Temperature protection: 70 After the servo is stalled, the output torque exceeds the overload torque and lasts for more than 8 seconds, and the protection torque is automatically output. The overload torque and protection time can be modified.
