    The thruster have arrived correctly. I tested them on the ROV and we are very happy with the result. The epoxy interior finish is very good and the power of the motors in relation to the size is quite good.

Product Description

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


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.


Model No. N20-1024GB
Driving voltage 5V DC
Resistance 25Ω
Inductance 4 mH
No-load speed 9000RPM
Reduction ratio 298:1
No-load output speed 25RPM
No-load current <60mA
Output torque 800g.cm
Run direction CW/CCW

About DC brushed motors

图片 2

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
