Model: Jkongmotor 42mm JK42BLS 12V 24V 36V BLDC Geared Motor with Planetary Gearbox 42x42mm
In general, there are three different types of gearboxes: concentric, parallel, and right angle.
The torque that is required in order to bring the gearbox in motion, in other words: in order to overcome the internal friction from standstill. The lower the number, the higher the efficiency and the more power of the motor is left for the movement.
Gearbox efficiency is the ratio of the output torque divided by the product of the input torque times the overall gear ratio. The overall gear ratio is the total gear reduction in the gearbox—the number of motor revolutions required for one revolution of the stem nut.
