Robot MarketPlace - Sabertooth 2 x 50HV Dual Motor Speed Controller

Sabertooth Dual Motor Speed Controllers - The Robot MarketPlace

The Sabertooth 2X50HV is one of the most versatile, efficient and easy to use dual motor drivers on the market. It is suitable for high powered robots - up to 120lbs in combat or 500lbs for general purpose robotics.

Out of the box, the Sabertooth can supply two DC brushed motors with up to 50A each. Peak currents of 100A per channel are achievable for a few seconds.

Overcurrent and thermal protection means you'll never have to worry about killing the driver with accidental stalls or by hooking up too big a motor.

Sabertooth allows you to control two motors with: analog voltage, radio control, serial and packetized serial. You can build many different robots of increasing complexity for years to come with a Sabertooth. Sabertooth has independent and speed+direction operating modes, making it the ideal driver for differential drive (tank style) robots and more.

The operating mode is set with the onboard DIP switches so there are no jumpers to lose. Sabertooth features screw terminal connectors - making it possible for you to build a robot without even soldering.

Sabertooth is the first synchronous regenerative motor driver in its class. The regenerative topology means that your batteries get recharged whenever you command your robot to slow down or reverse. Sabertooth also allows you to make very fast stops and reverses - giving your robot a quick and nimble edge.

Sabertooth has a built in 5V BEC that can provide power to a microcontroller or R/C receiver. The lithium cutoff mode allows Sabertooth to operate safely with lithium ion and lithium polymer battery packs - the highest energy density batteries available.

Sabertooth's transistors are switched at ultrasonic speeds (32kHz) for silent operation.

Very Happy This Product.

I bought one of these to run my Robo Magellan navigation robot. (which is made from a powered wheelchair base)
I found that it works better than the original chair controller, and provides nearly twice the power to the wheels. I give these 5 stars and plan to buy 2 more for my other robot projects.

Very good speed control for 2X mid size motors. A bit tricky to find out how you control it by R/C or microcontroller. However the site has a wizard to figure out how you configure your setting:
