JGB37-520 Brushed DC Gear Motor with Hall Encoder

The JGB37-520 is a compact brushed DC gear motor with an A/B incremental Hall encoder, a metal reduction gearbox, a 6mm D-shaped output shaft and reversible rotation. Choose a 12V or 24V motor, the required no-load output speed, and a motor-only or accessory package for robotics, small mechanisms and electronics projects.

The selectable speeds are 7, 12, 22, 35, 45, 66, 107, 200, 319, 600 and 960 RPM. These options match the supplier’s 6000RPM motor-before-reduction series. Output RPM is measured without load; speed decreases under load. A bracket shown in a photograph is included only when the selected Package names a bracket.

Construction and Speed Control

  • Metal reduction gears in a multi-stage arrangement, copper winding, permanent-magnet motor and carbon brushes.
  • PWM speed control is possible with a compatible external brushed-DC controller. A controller is included only in the specified packages.
  • Swap only the red and white motor power leads to reverse rotation. Keep encoder and controller supply polarity correct; stop the motor before changing direction.
  • The gear ratio determines the speed/torque trade-off. Reducing speed electrically does not provide the same torque increase as selecting a higher reduction ratio.

Mechanical Specifications

Parameter Specification
Brand / model Jiali Motor / JGB37-520
Motor type Brushed DC gear motor with A/B incremental magnetic Hall encoder
Rated supply 12V DC or 24V DC, according to selected variant
Gearbox diameter 37mm
Motor body diameter / section length 32mm / 22mm
Gearbox length L 1929mm, depending on reduction ratio
Output shaft 6mm diameter, 15.5mm projection; 12mm flat length; 5.5mm across flat
Shaft diameter tolerance 0.03 / 0.05mm, as marked on the drawing
Locating boss 12mm diameter 6mm height
Mounting Six M3 threaded holes on a 31mm pitch circle; drawing specifies 3.5mm depth, photograph specifies 4mm. Verify screw engagement on the actual motor.
Encoder and cable 32mm encoder diameter; rear assembly projection 11.75mm; PH2.0 six-pin cable approximately 144mm long
Shaft offset 7mm from motor centreline
Reduction ratios in supplier reference 6.25:1810:1; not every reference ratio is selectable
Motor-only weight Approximately 144170g according to ratio; overview states approximately 170g
Supplier overview ratings 2.410.8W and 0.150.65A across illustrated series; use the series-specific tables below
Supplier operating claims 10C to 70C; overview lists 24-hour use. Actual duty suitability depends on load and cooling.
Noise Supplier states approximately 55dB, varying with speed and load; measurement conditions are not specified

Dimensions are supplier reference measurements and may vary. Motor appearance and components can differ between versions. The encoder supplies feedback signals; closed-loop control requires a suitable external controller. Encoder temperature claims do not extend the complete motor operating range.

6000RPM Motor Series Performance Reference

This series matches the selectable speed family. The tables also retain the supplier’s non-selectable reference speeds (85, 28, 15 and 9.5 RPM) for completeness; they do not create additional purchase options. Values are supplier data, not independent test results. Torque is in kgfcm, not kilograms of lifting capacity.
