High torque worm gearbox reducer N20 DC motor with magnetic encoder

Description:

This is a N20 DC brushed motor attached with a worm gearbox.

We have different ratios for choosing.

The encoder is magnetic encoder, and motor’s resolution is determined by magnet poles on the magnetic wheel.

For each pair of magnet poles, that’s 1 PPR.

We have 7PPR and 12 PPR for choosing.(7 magnet poles and 12 magnet poles)

There are 6 pins on this connector:

1. M1 motor power1

2. - encoder power-(GND)

3.A signal pin A

4.B signal pin B

5.+ encoder power+(5V DC)

6.M2 motor power2

About DC brushed motors:

DC brushed motors are most commonly used motors on the market.

It has electrical brush inside, and it has positive and negative pins (+ and -)

DC motor’s speed can be controlled with different gear ratios, or PWM control. (Pulse-Width Modulation)

With gearbox torque boost, DC motor can reach much higher torque, compared to motor’s original torque.

Advantage of DC brush motors:

1. Cheap price

2. Small size

3. Easy to connect, easy to use

4. Commonly used

5. Fast speed

6. High efficiency (compared to stepper motor)

DC motor with gearbox:

Gearbox can boost motor’s torque, and reduce motor’s speed

We have different gear ratios for you to choose, also gearbox’s efficiency is related to gear levels.

Output torque=original torque*gear ratio* gearbox efficiency

Output speed= original speed/gear ratio
