JGB37-520 DC Gear Motor, 12V/24V, 7–960 RPM, 37mm Metal Gearbox and 6mm D-Shaft

JGB37-520 Brushed DC Gear Motor

The JGB37-520 is a compact brushed DC gear motor with 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.
• For the bare two-terminal motor, reversing motor-lead polarity reverses rotation. With a controller fitted, use its direction control and keep controller supply polarity correct.
• 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

Dimensions are supplier reference measurements and may vary. Motor appearance and components can differ between versions. No encoder, controller input-frequency specification or closed-loop positioning function is specified.

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 kgf·cm, not kilograms of lifting capacity.

24V — 6000RPM Before Reduction

10000RPM Motor Series — Additional Supplier Reference Only

The supplied image also includes the following higher-speed motor series. This is reference information only: it is not a separately selectable series in this listing. Do not apply these figures to a purchased 6000RPM-series variant, even where an output RPM happens to overlap.

Optional Mounting Bracket

The illustrated L-bracket is 1.5mm thick, approximately 40mm wide, with a 40mm base and 47mm upright. The motor mounting pattern is marked 31mm pitch diameter with six 3.2mm holes and 6.3mm recesses. The central opening is marked 2 × R6.5 with 14mm centre spacing. The base drawing shows four 3.5mm holes at 24 × 30mm spacing and an 8mm side offset; the upright includes a 20mm reference dimension. The bracket is supplied only with the applicable Package.

Wiring and Use

Use a DC supply matching the selected motor voltage. In the illustrated controller arrangement, connect the supply to the controller's power input with correct polarity, and connect the controller motor output to the two motor terminals. The illustration shows red positive and black negative motor leads, a speed knob, a reversing switch and a supply adapter connection. Confirm actual terminal labels before powering on. Never reverse the controller's power input to reverse the motor, and stop the motor before changing direction.

Choose the motor by its rated-load torque rather than its stall torque. Do not overload, stall or operate close to stall: the motor or gears can be damaged. Loads above the rated condition reduce speed. Lowering electrical speed can also reduce available torque. Controller ratings, adapter mains-input rating, plug type and included cable/connector details are not fully specified in the supplied listing; verify these details for the selected accessories.

Torque and Unit Reference

For a static load, required torque in kgf·cm equals load in kgf multiplied by lever radius in cm. The supplier illustrates a 10kg load: 10kgf·cm at a 1cm radius, or 100kgf·cm at a 10cm radius. This is an explanatory example, not this motor's lifting rating. Allow for friction, acceleration and the mechanism's actual operating load.
