SyRen 20A regenerative motor driver
This product has been replaced by the
The SyRen motor driver is one of the
most versatile, efficient and easy to use motor drivers on the market.
It is suitable for medium powered robots - up to 50lbs in
combat or 180lbs for general purpose robotics.
Out of the box, the SyRen 20 can supply a single DC brushed motor
with up to 20A continuously. Peak currents of 30A 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.
With just one SyRen driver you can control a motor with:
analog voltage, radio control, serial and packetized serial.
You can build many different robots of increasing complexity
for years to come with a SyRen. Owning two SyRens allows you
to build differential drive (tank style) robots because they
can work in tandem with built in mixing.
The operating mode is set with the onboard DIP switches so there are no
jumpers to lose. The SyRen features screw terminal connectors - making
it possible for you to build a robot without even soldering.
SyRen 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. SyRen also
allows you to make very fast stops and reverses - giving your robot a
quick and nimble edge.
SyRen has a built in 5V BEC that can provide power to a microcontroller
or R/C receiver. The lithium cutoff mode allows SyRen to operate safely
with lithium ion and lithium polymer battery packs - the highest energy
density batteries available.
SyRen's transistors are switched at ultrasonic speeds (32kHz), meaning
no one will be able to hear your robot ninja army approaching.
Use of our motor drivers with cheap AC adapters is not recommended.
Use a battery or at least put a battery in parallel with a DC supply.
Servo pigtails are available here.
