Can realize the infinite speed adjustment Is accomplished by continuous change of frequency. Change the rotational torque, under the condition of the same power, the faster the speed of gear, shaft torque of the smaller, vice . It can be at the same time to improve the output torque, torque output ratio according to the motor output by reduction ratio. Deceleration of the motor speed is through a adjustment of the motor. separate the two meshing gears, achieve the goal of separate the motor and load. No load Speed: 30 rpm Torque: 1 m Type: Gear Motor Voltage: 12V Commutation: Brush Type: Brushed DC Motor No load Current: less than equal 0.5A Reduction Ratio: 600 Maximum Torque (kg.cm): 21 Application:Open the window, door, Mini winch,high-end toys, electric products, automobile automatic facilities, intelligent system, automation control and other industrial drives, etc. Place of Application: Intelligent Driving Device Colour:As Shown Material:Metal Package Contents: 5 x High Torque Turbo Worm Geared Motor DC Motor Only the above package content, other products are not included.
