Universal Aluminum Mounting Hub for 5mm Shaft Pair

The set includes two hubs, two #4-40 set screws for securing the hubs to motor shafts, and one 0.05″ Allen wrench for use with the set screws. Each hub has four threaded mounting holes for #4-40 screws (not included). We have an assortment of universal mounting hubs available, spanning several shaft sizes and featuring mounting holes threaded for metric or imperial screws:

Stepper Motor: Bipolar, 200 Steps/Rev, 20x30mm, 3.9V, 600mA. This small NEMA 8-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution).

Stepper Motor: Bipolar, 200 Steps/Rev, 20x30mm, 3.9V, 600mA

Each phase draws 600 mA at 3.9 V, allowing for a holding torque of 180 g-cm (2.5 oz-in). With a weight of 60 g, this is one of the smallest stepper motors we carry. Overview. Stepper Motor: Bipolar, 200 Steps/Rev, 28x32mm, 3.8V, 670mA. This NEMA 11-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution).

Stepper Motor: Bipolar, 200 Steps/Rev, 28x32mm, 3.8V, 670mA

Stepper Motor: Bipolar, 200 Steps/Rev, 35x26mm, 7.4V, 280mA. Overview This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution).

Stepper Motor: Bipolar, 200 Steps/Rev, 35x26mm, 7.4V, 280mA

Each phase draws 280 mA at 7.4 V, allowing for a holding torque of 650 g-cm (9 oz-in). The motor has four color-coded wires terminated with bare leads: black and green connect to one coil; red and blue connect to the other. SN754410 Motor Driver IC. The SN754410NE from Texas Instruments is a quadruple half-H driver that can be used for bidirectional control of two DC motors or to control a single bipolar stepper motor.

SN754410 Motor Driver IC

You can use this item as a replacement part, to stack on an existing motor controller, or to make your own motor or other high-current device controller. This integrated motor driver has the same pinout as the L293 that is popular in robotics applications, and the SN754410NE has the additional benefits of built-in protection diodes across the power transistors and output current capability of 1 A per driver. Sanyo LB1836M Motor Driver IC. Discontinuation notice: This product has been discontinued.

Sanyo LB1836M Motor Driver IC

We recommend the much newer DRV8835 dual motor driver carrier as a higher-performance alternative. Description The Sanyo LB1836M is a dual low-voltage H-bridge that can be used for bidirectional control of two DC motors or one bipolar stepper motor. With an operating voltage as low as 2.5 V for logic and 1.8 V for the motor(s), this controller is great for small motors powered from a single Li-based battery or 2-6 NiMH or alkaline cells. The peak current is up to 1 A per channel, but thermal dissipation usually limits the available continuous current to around 0.5 A (this depends on the PCB layout and heat sinking). The motor driver features thermal shutdown that can help the chip withstand over-current and short-circuit situations. Key Features and Specificactions People often buy this product together with: Baby Orangutan B-328 Robot Controller. Overview The Baby Orangutan is a complete control solution for small robots, all packed into a tiny 1.2" x 0.7" 24-pin DIP package.

Baby Orangutan B-328 Robot Controller

Its compact design eliminates bulkier components such as the LCD and switches while retaining the most essential features of the Orangutan robot controller line: a programmable ATmega48 or ATmega328P AVR microcontroller and a dual H-bridge for direct control of two DC motors. This integrated motor driver sets the Baby Orangutan B apart from similarly-sized microcontroller boards from other manufacturers. Two on-board indicator LEDs, a trimmer potentiometer, a 20 MHz resonator, and reverse battery protection round out the basic hardware features of the Baby Orangutan.

The removal of the larger Orangutan components also allows for a significantly improved manufacturing process that allows Pololu to offer the Baby Orangutan B at a very affordable price. Features ATmega48, ATmega168, and ATmega328 comparison Included components.
