Feature:1. The motor adopts stainless steel output shaft with a diameter of 8mm, a high accuracy structure, and runs smoothly and silently.2. The shell of the geared motor is made of all metal, which is wear resistant and not easy to rust, and has good thermal conductivity.3. With brass turbine worm and double ball bearings, the noise generated by the motor running is small.4. After the gear is ground, heat treated and filled with imported lubricating oil, has low friction coefficient and high load carrying capacity.5. The DC geared motor is equipped with governor and has strong torsion, suitable for curtain machines, billboards, window openers, etc.Specification:Item Type: Geared MotorModel: 5840-31ZYWorking Voltage: 12VShaft Length: Approx. 15mm / 0.6in, D shaft length approx. 13mm / 0.5inShaft Diameter: Approx. 8mm / 0.3in, D shaftVoltage V1212121212121212Rated Speed RPM4002001305030201210Rated Torsion Kg.cm3.46.2102040607070Rated Current A1.61.61.61.61.61.61.61.6Maximum Torsion Kg.cm8.516255070707070Stall Current A6.56.56.56.56.56.56.56.5CCM2 DC Motor Governor Parameters: DC motor regulator CW and CCW controlThis governor uses PWM speed control technology, which has the characteristics of high conversion efficiency, wide speed range and stable performance. All of them use imported semiconductor original chips, and the circuits are stable and reliable after a number of tests such as voltage, current, and functions before leaving the factory.Model: CCM2Working Voltage: DC 10V-30VControl Power: 12V x 3A=36W, 24V x 3A=72W, 24V, maximum 120WRated Current: 3AMaximum Current: 5APWM Pulse Width Adjustment Range: 5%-95%Potentiometer: Resistance value B10K, wire length is approx. 20cm / 7.9in, opening approx. 8mm / 0.3inOutput Voltage: About 0-100% of the input voltageSpeed Governor Size: Approx. 74 x 47 x 28mm / 2.9 x 1.9 x 1.1inPotentiometer is used for speed regulationCW and CCW switche is used to control forward, reverse, and stop.Package List:1 x Motor1 x Governor1 x CW and CCW Switch1 x Knob Cap1 x Washer1 x Bracket4 x Mounting ScrewNote:Motor:1. When using the motor, there should be no restrictions. For example, the adhesive should not flow into the bearing through the rotating shaft, which will affect the run of the motor.2. In order to prolong the service life, do not overload or hang objects that hinder rotation at the shaft end.3. Manufactured into an eccentric heavy radiation load, which is harmful to the life of the motor.4. Do not store in high temperature or extreme humidity, and do not place in corrosive gas, which will reduce the effect of the motor.5. When soldering is required on the positive and negative motor terminals of the power supply, the temperature of the soldering iron is 34040, and the heating time is less than 3s. Do not deform the plastic. Let the solder points flow into the motor or break the end of the wire during work to make the motor function. decline.6. The maximum bearing capacity of the gear is 70KG, blocking is forbidden, and the motor may be burnt if it is blocked for a long time.7. Supply the specified power and be sure that it is within the range of measurable requirements.8. The installation of pulleys or gears should not be abnormally aggravated when pressed in.9. When installing the motor, if the screw is too long, it will cause contact between the motor and the rotor, thereby affecting the characteristics.Governor:1. The input of the DC motor speed controller is direct current, and cannot be directly connected to alternating current (such as household 220V AC motors).2. The positive and negative poles of the DC power supply cannot be reversed.3. The motor can be positive or negative. When the running direction is not suitable, the direction can be changed by adjusting the wire sequence.4. The potentiometer knob can change the duty cycle of the governor output, thereby changing the motor speed.
