This gearmotor is a miniature high-power, 6 V brushed DC motor with long-life carbon brushes and a 986.41:1 metal gearbox, making it a great choice for applications requiring fine control at very low speeds. It has a cross section of 10 × 12 mm, and the D-shaped gearbox output shaft is 9 mm long and 3 mm in diameter. This version also has a 4.5 × 1 mm extended motor shaft.

This gearmotor is a miniature high-power, 6 V brushed DC motor with long-life carbon brushes and a 9.96:1 metal gearbox. It has a cross section of 10 × 12 mm, and the D-shaped gearbox output shaft is 9 mm long and 3 mm in diameter. This version also has a 4.5 × 1 mm extended motor shaft.

This gearmotor consists of a low-power, 12 V brushed DC motor combined with a 4.4:1 metal spur gearbox, and it has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 211.2 counts per revolution of the gearbox’s output shaft.

The FS90 analog servo from FEETECH is a great general-purpose micro servo at a great price. Servo horns and associated hardware are included.

Key specs at 6 V: 0.10 sec/60°, 21 oz-in (1.5 kg-cm), 9.0 g.

Add quadrature encoders to your 20D mm metal gearmotors (extended back shaft version required) with this kit that uses a magnetic disc and Hall effect sensors to provide 20 counts per revolution of the motor shaft. The sensors operate from 2.7 V to 18 V and provide digital outputs that can be connected directly to a microcontroller or other digital circuit.

This NEMA 17 pancake bipolar stepping motor from Sanyo features an integrated encoder. The stepper motor itself has a 1.8° step angle (200 steps/revolution) and each phase draws 1 A at 5.4 V, allowing for a holding torque of 1.9 kg-cm.

This NEMA 17-size pancake bipolar stepping motor from Sanyo features an integrated high-resolution (1000 P/R) quadrature encoder. The stepper motor itself has a 1.8° step angle and each phase draws 1 A at 3.5 V, allowing for a holding torque of 0.85 kg-cm.

The Tic T825 USB Multi-Interface Stepper Motor Controller makes basic control of a stepper motor easy, with quick configuration over USB using our free software. The controller supports six control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), quadrature encoder, and hobby radio control (RC).

The FEETECH FT5335M servo is all about torque. This 1/4-scale digital servo can deliver an incredible 550 oz-in of torque at 7.4 V or 480 oz-in at 6 V thanks to its powerful motor and all-metal gear train. The FT5335M is a high-voltage servo, offering an operating voltage range of 6 V to 7.4 V. Servo horns and associated hardware are included.

These universal aluminum mounting hubs allow you to mount custom wheels and mechanisms to 8 mm diameter motor shafts. The set includes two hubs, four M3 set screws for securing the hubs to motor shafts, and one 1.5 mm Allen wrench for use with the set screws.
