N20 DC Brushed Motor With 1024 Gearbox, Output Shaft Can Be Customised

N20 DC Brushed Motor With 1024 Gearbox, Output Shaft Can Be Customised

Description

This is an N20 DC motor with a 1024 gearbox.
The N20 DC motor is also a brushed DC motor with a no-load speed of approximately 15,000 RPM for a single motor.
When the motor is connected to a gearbox, it runs slower and with more torque.
The output shaft of this motor is a D-shaft and the customer can also choose a threaded shaft, if required.
Gearboxes are available in the following gear ratios: 10:1,30:1,50:1,100:1,150:1,300:1,323:1,483:1,500:1,668:1,945:1,1000:1, the customer can choose the gear ratio according to his needs.
When the gear ratio is less than 600:1, the gearbox height can be adjusted to 6 mm (short version).
The output can be a D-shaft with a diameter of 3mm*D2.5mm, or an M3 leadscrew, or other customised shaft type.

About DC brushed motors

DC brushed motors are the most commonly used motors on the market.
DC motors have brushes inside, l positive and negative poles (+ and -).
The speed of the DC motor can be controlled with different gear ratios or with PWM (pulse width modulation)
By means of a torque boost from the gearbox, the DC motor can achieve higher torques than the original torque of the motor.
It can also be installed in the following positions according to customer requirements:
1024GB Series + N20 DC motor

Application

Medical devices, robotics field, smart home, automotive drive, aircraft, consumer electronics, industrial automation, optical instruments and equipment field, etc.

Advantages of DC brushed motors

1. cheaper (compared to stepper motors)
2. Smaller size
3. Direct connection, easy to use
4. Wide range of use
5. Fast speed of rotation
6. Higher efficiency (compared with stepper motors)

Customization service

Out of the shaft length (the tail can be out of the shaft matching encoder),
The voltage,
The rotational speed,
Outlet mode,
And connectors and so on

Lead time and packaging information

Lead time for samples:
Standard motors in stock: within 3 days
Standard motors not in stock: within 15 days
Customized products: About 25~30 days (based on complexity of customization)
Lead time for building a new mold: generally about 45 days
Lead time for mass production: based on order quantity
