Vantec has many winners in
Battlebots, Robot Wars and some educational fare wins. Most purchases for Battlebots
or competitive "tank
style" steered robots use our RDFR
series which is a complete DUAL speed controller including mixing for vehicles with right/left motors.
These successful designs and actual examples understand the importance of optimized gearing to
achieve an efficient operating RPM for the motor.
This Selection Guide includes provision for
over-voltaging the motor and anticipates your 'bot will properly
gear a pair of motors OR perhaps a
total of 4 or 6 motors. When there is more than
one motor per side consider how to wire the motors. Motors that are hard coupled via
gears, sprockets and shafts must be wired in series to force them to share the torque
load. That means the battery voltage required is motor voltage intended times number of motors
series'ed. The current load is that of a single motor. For hard coupled designs
consider that using one proper sized motor is usually more efficient than coupling two
smaller motors.
On the other hand if there are two right side motors each independently
coupled to it's own wheel, the motors should be wired in parallel. Parallel wired motors
will be powered by a battery voltage equal to the intended motor voltage but the current draw
will increase by the number of motors on a side.
If you are building a heavywight or using extreme motors this Guide
may recommend RSFR single controllers. Two of the singles may be
operated independently and still may utilize the mixing function.
