These “Grade B Johnson DC Motors” are in fame for their performance even at a low price compared to “Grade A Quality Johnson DC Motors”. (to know the difference between the two motors please read the Note below)

It is a simple DC motor featuring metal gearbox for driving the shaft of the motor, so it is a mechanically commutated electric motor which is powered from DC supply. The Johnson Geared Motors are known for their compact size and massive torque-speed characteristic.

The Johnson Motor comes with side shaft also known as an off-centered shaft and six M3 mounting holes. The shaft of the motor equips metal bushes which makes these DC gear motors Shaft wear resistant. The shaft of the motor has a hole for better coupling.

The motor will run smoothly between the voltage range 6 to 18 V DC and give you 300 RPM at 12V supply. It provides the torque of 11.7 kg-cm at 300 RPM.

Please note that this motor will have a ±20% error in the RPM.

The Johnson Geared Motor gives very good torque at an affordable price hence they are widely applicable in Pan/Tilt camera, auto shutter, welding machines, water meter IC card, grill, oven, cleaning machine garbage disposers, household appliances, slot machines, money detector, automatic actuator, coffee machine, towel disposal, lighting coin refund devices, the peristaltic pump and so on.

Also, they are best suitable with highly developing capable robots or robotic platform, various automation purposes.

Note: 

We are selling 2 types of Johnson Motors as “Johnson Geared Motor – Grade A Quality” and “Johnson Geared Motor – Grade B“, the only difference between them is the quality of materials used for manufacturing the motor. All other specification including look, dimensions, working etc. are same. The “Grade A Quality” motors shows slightly more torque count than “Grade B” Johnson Motors and hence dominates “Grade B” quality motors. So, the Johnson Geared Motor – Grade A Quality costs little more than Johnson Geared Motor – Grade B.

We offer the range of Johnson motors with different RPM as shown below, click on RPM numbers for more information

DHT11 Humidity Sensor. We offer these at reasonable rates.

A humidity sensor, or hygrometer, is an electronic device that measures and reports the moisture level in the air. These sensors are used in a wide range of applications, from domestic appliances to industrial manufacturing, to monitor and control environmental moisture levels. Humidity can be expressed as absolute humidity (AH), the mass of water vapor per unit volume of air, or relative humidity (RH), the ratio of water vapor in the air compared to the maximum amount the air can hold at a given temperature

This BMS (Battery Management System) ??? a battery management system that is designed to monitor the status of batteries, control the battery charge/discharge process, etc. Four 18650 batteries can be connected simultaneously to the HX-4S-BMD1 module. The features of this charge controller are protection against short circuit (short circuit) and protection against over-discharge (overcharge). Also, a feature of the module is to turn off the power supply for the batteries when the maximum capacity of at least one battery is reached. The maximum operating current of this BMS controller is 20 A, and the quiescent current reaches up to 10 ??A. The battery charge is switched off when the voltage reaches 4.25 ??? 4.35 V, and the discharge when the voltage drops to 2.3 ??? 3.0 V. If the maximum permissible value of the supply voltage is exceeded, the charge controller activates the ???protection??? mode. In order to restore the module, it is necessary to re-apply voltage to the input of the BMS board or wait a while until the charge controller automatically disables protection. 4S 14.8V 20A Lithium battery Protection Board connection Diagram BMS solder instruction: B+ connected battery positive; B1 the connect point between battery 1 and battery 2; B2 connect the point between battery2 and battery 3; B3 Connect the point between battery 3 and battery 4; B- connect to battery negative end; P- + connection charge / discharge positive; P- connection charge / discharge negative; Small size designed for a four-cell battery pack.
