Motors

These cylindrical brushed DC gearmotors are available in a wide range of gear ratios. The gearmotors all have the same 25 mm diameter body and 4 mm diameter gearbox output shaft, so it is generally easy to swap one version for another if your design requirements change (though the length of the gearbox tends to increase with the gear ratio).  Specifications    Tutorial

The TowerPro SG90 mini servo is lightweight, high-quality and lightning-fast. The servo is designed to work with almost all radio control systems. The SG90 mini servo with accessories is perfect for R/C helicopter, plane, car, boat and truck use. It equips Carbon Fiber Gears which makes the servo motor much lighter than the same metal gear motor. For small load applications using the metal gear, servo motor adds on unnecessary weight, so we suggest using these lightweight plastic gear servo motors. The TowerPro SG90 9g Mini Servo is a 180° rotation servo. It is a Digital Servo Motor that receives and processes PWM signal faster and better. It equips sophisticated internal circuitry that provides good torque, holding power, and faster updates in response to external forces.

Measuring 25 mm (0.98″) in diameter, these motors offer great capabilities in a small package. They are available in a range of gear ratios.  With quadrature encoders added to the micro metal gear motors (with extended back shaft), these motors use a magnetic disc and hall effect sensors to provide 11 counts per revolution of the motor shaft. The sensors operate from 3.3 V to 5 V and provide digital outputs that can be connected directly to a micro controller or other digital circuit.

Measuring 37 mm (1.46″) in diameter, these 12V and 24V motors are capable of offering huge amounts of torque in a reasonable package. They are available in a range of gear ratios.  With quadrature encoders added to the micro metal gearmotors (with extended back shaft), these motors use a magnetic disc and hall effect sensors to provide 11 counts per revolution of the motor shaft. The sensors operate from 3.3 V to 5 V and provide digital outputs that can be connected directly to a microcontroller or other digital circuit. NOTE: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. Stalls can also result in rapid (potentially on the order of seconds) thermal damage to the motor windings and brushes; a general recommendation for brushed DC motor operation is 25% or less of the stall current.

Add more power to your robot with this metal-geared MG90S servo. The tiny little servo can rotate approximately 90 degrees (45 in each direction), and works just like the standard kinds you're used to but smaller. You can use any servo code, hardware or library to control these servos. Good for beginners who want to make stuff move without building a motor controller with feedback & gear box, especially since it will fit in small places.  Please note, this servo will 'hold' the position even when no signal is sent!To control with an Arduino, we suggest connecting the orange control wire to pin 9 or 10 and using the Servo library included with the Arduino IDE. Position "0" (1.5ms pulse) is middle, "90" (~2ms pulse) is all the way to the right, "-90" (~1ms pulse) is all the way to the left. NOTE: Operating servos at or near Stall Torque is not recommended and will shorten the life of your servo drastically.

Mini Stepper Motor for Lighter projects requiring precise geared control. The motor has a reduction ratio of 64:1, so it offers a decent torque for its size at speeds of about 15 RPM. It is a unipolar stepper motor which has 5-wires. As stated before the pack contains ULN2003 Stepper Motor Driver which is a Mini Stepper Motor Driver. The main purpose of ULN2003 is to amplify the control signals from the Arduino, so as to drive the 28BYJ-48 Stepper Motor. If you will give the ULN2003 stepper driver a certain pulse signal, it will drive step motor to a certain angle. The control of Stepper Motor movement angle is done by controlling the number of stepper motor driver pulses. The speed of the stepper motor rotation is also controllable by controlling the frequency of the pulses. Specifications Reduction Ratio: 1:64 Step Angle: 5.625 Voltage: 12V Diameter: 28mm 5-Line 4-phase can be driven by ordinary ULN2003 chip ,can also be connected in phase 2 development board used for supporting the use of a direct plug and easy to use stepper motor used in the development board Resources Datasheet Sample Code Tutorial  

With a cross section measuring only 10 × 12 mm (0.39″ × 0.47″), these small brushed DC gearmotors are available in a wide range of gear ratios—from 5:1 up to 1000:1—and with five different motors: high-power 6 V and 12 V motors with long-life carbon brushes (HPCB), and high-power (HP), medium power (MP), and low power (LP) 6 V motors with shorter-life precious metal brushes. With the exception of the 1000:1 gear ratio versions, all of the micro metal gearmotors have the same physical dimensions (though the terminal size and separation on the HPCB versions differ slightly from the other versions), so it is generally easy to swap one version for another if your design requirements change.  Stall Current: 0.55A (6V) No-Load Current: <0.06A (6V) At Load Current: 0.17A (6V) Shaft Diameter: 3 mm Specifications Variant Reduction Ratio Load Speed (RPM) Max.

MG996R is an upgraded version of MG995 servo. The new PCB and IC control system which makes it far more accurate. Its internal gearing and motor are also upgraded to improve dead bandwidth and centering. It is a great choice for 1/10 buggy and airplane helicopter, RC-cars from 10 to 6-th scale truggy and monster and many RC model. This high-torque standard servo now comes in a metal-gear flavor, for extra-high torque (9.4 kg-cm!) and reliability! It can rotate at least 180 degrees (90 in each direction) with a classic 1.5-2.5ms pulse. You can use any servo code, hardware or library to control these servos. To control with an Arduino, we suggest connecting the orange control wire to pin 9 or 10 and using the Servo library included with the Arduino IDE. Position "0" (1.5ms pulse) is middle, "90" (~2ms pulse) is all the way to the right, "-90" (~1ms pulse) is all the way to the left. The default servo pulse widths (usually 1ms to 2ms) may not give you a full 360 degrees of motion. In that case, check if you can set your servo controller to custom pulse lengths and try 0.75ms to 2.25ms. You can try shorter/longer pulses but be aware that if you go too far you could break your servo! NOTE: Operating servos close to or at stall torque reduces their life and will permanently damage them beyond repair.

These brushed DC gearmotors are compact and affordable — perfect for building a quick, miniature robot. They are intended for use at 4.5 V, though in general, these kinds of motors can run at voltages above and below this nominal voltage, so they should operate comfortably in the 3 V to 6 V range. The plastic gearbox is protected by a built-in safety clutch that will typically slip before the gear teeth can shear. For rugged and harsh environments, please use our 65mm Rugged Wheel Set Specifications Wheel Diameter: 66mm No-Load Speed (6V): 200 RPM (±10%) @ 0.2A No-Load Speed (3V): 90 RPM (±10%) @ 0.15A Maximum Efficiency: 2.0 kg-cm / 170 RPM / 0.6A Reduction Ratio: 1:48 Tutorial  

Mini Stepper Motor for Lighter projects requiring precise geared control. A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. The motors rotation has several direct relationships to these applied input pulses. The sequence of the applied pulses is directly related to the direction of motor shafts rotation. The speed of the motor shafts rotation is directly related to the frequency of the input pulses and the length of rotation is directly related to the number of input pulses applied.One of the most significant advantages of a stepper motor is its ability to be accurately controlled in an open loop system. Open loop control means no feedback information about position is needed. This type of control eliminates the need for expensive sensing and feedback devices such as optical encoders. Your position is known simply by keeping track of the input step pulses.
