Product description: Geared motor 37Dx73L 131:1 12 V 76 RPM + CPR 64 encoder
A high power Polol engine with a 131:1 gearbox.Its speed is 76 rpmandits torque is 45 kg*cm (4.41 Nm). It is equipped with a quadrature encoder with a resolutionof 64 pulses per revolution (aftertransmission of 8400 pulses per revolution). The12-voltmotor draws150mAwithout load and5.5Awith the shaft stopped.
Motor accessories
In our offer you will also find dedicated accessories:
Special mountings and 6 mm Hubs formountingwheels have been designed for theengines.
Engine dimensions
The engine has a diameter of 36.8 mm and an overall length of 73 mm. Detailed data are given in the technical drawing.
Where the dimension L is 26,5 mm.
Encoder in the motor
A sensor based on the Hall effect detects pulses on a rotating magnetic disk at the back of the engine. Square encoders allow measurement with a resolution of 64 pulses per motor shaft revolution. After the gearbox, this is the right number of times more.
The outputs:
- Red- motorpower supply
- Black -engine power
- Green- encoder masspotential
- Blue- Encoderpower supply(3.5 V - 20 V)
- Yellow -encoderoutputA
- White- encoder Boutput
The figure shows the signal from both encoder channels. The B signal is shifted in phase relative to the A signal by 90 degrees.
