Description: Rotary Telescopic Thrust Reducer Gear DC Motor 12V Worm Cyclotron Telescopic Structure with Encoder.    Specification: Features:worm rotary structure, gear reduction mechanism, strong magnetic torque motor;  Outer diameter:∮24.0mm×105mm—120mm;  Output structure:5*5 square head shaft;  Weight:about 75 grams;  Rotary expansion rate:the motor is rotated 6 times for one round;  Application:adult products, smart home appliances systems, smart educational toys, etc.  Voltage:DC 12V;  No load expansion number of rounds:83±10% round;  No-load speed:500±10%rpm;  No-load current:≤230mA;  Rated torque:1.0kg.cm;  Rated speed:330±10%rpm;  Rated current:1.2A max;  Rated power:3.5W (max 4.0W);  Stall torque:≥3.0kg.cm;  Max permissible thrust:≤60N;  Stall current:≤3.3A;  Number of encoder:11x18.837 = 207.207;  Ratio:1:19 (18.837);    Type: 1:gear motor (standard type);  2:gear motor+No welding PCB;  3:gear motor+encoder;  4:2A Non-polar governor;  5:DC 5V power.    Features: 1.  Pure copper wire winding.  The rotor is made of pure copper, small resistance, strong electrical conductivity, increasing the torque of the motor.  2.  Plastic turbine telescopic rotation mechanism.  Low noise, stable performance, high efficiency, low thrust conversion loss.  3.  Metal gear reduction mechanism.  High strength, stable transmission, high efficiency and high torque.  4. It is not recommended to use frequent blocking or startup and positive and negative rotation in the process of use, which will greatly reduce the service life.    Product type: 1- standard telescopic rotary motor.  Standard construction, the motor has 2 electrodes behind it, which can be welded by itself or connected directly by electricity.  2- no welding PCB board structure.  On the basis of the standard structure, an anti-interference PCB board is added, the output is ph2.0-2pin terminal head, and the terminal line is matched to facilitate the direct connection of customers, so as to avoid motor damage caused by welding or scald yourself.  3- telescopic rotary motor with encoder structure.  On the basis of the standard structure, the motor is equipped with a AB phase hall encoder. The encoder is equipped with a shielding shell. The output of the AB phase is high and low power square wave.    Package Included: 1:gear motor (standard type);  2:gear motor+No welding PCB;  3:gear motor+encoder;  4:2A Non-polar governor;  5:DC 5V power;  (Please note that the package inlcuded one type only.)
