DC Motor 37GB-545 12V 4rpm

The DC Motor 37GB-545 12V 4rpm is a very slow DC gear motor from the 37GB series, pairing a brushed DC motor with a 37 mm reduction gearbox. At 12 V its output shaft makes about 4 turns per minute, one full turn every 15 seconds. This gentle, steady motion suits rotating displays, time-lapse rigs, solar trackers and kinetic art that must move slowly without extra gearing.

What's in the Box

• 1 × DC Motor 37GB-545, 12 V 4 rpm

Tip: Even at this low speed, use a motor driver such as an L298N rather than a microcontroller pin, because the motor current is far above what a pin can supply. Mount it with a 37GB motor bracket and fix the load firmly to the shaft.
