FREQUENTLY ASKED QUESTIONS:

VRP DYNO 2.0

Q.   What voltage is needed to operate the VRP Dyno?

A.   Normal Operating voltage is 18 Volts DC, However it will operate on 8 to 22 Volts DC.

Q.   Why should I apply 1.4 volts more than I need to the VRP Dyno?

A.   The VRP Dyno needs 1.4 Volts of the power supply voltage to operate. So 19.4 V will get you 18 at the terminals.

Q.   What current is needed to operate the dyno?

A.   3 to 4 Amps when running T-Jets to RO.  5 to 7 Amps  when running Neo and Open Class Cars

Q.   Can the dyno test the 12 Volt G-Jet cars?

A.   Yes, to do this, apply 13-14 volts DC to the input power tabs.

A word about Dyno’s
A Dyno measures mechanical power or driving torque of a motor. A unit cannot be called a Dyno if it does not provide a load for the motor it is being driven by. Many today are calling their units dyno’s but they are only speed checkers reading the RPM’s of the motor or the speed of the roller. Either case if there is not a load on the motor, it cannot be called a Dyno.


VRP BALANCER

Q.   How does the VRP precision balancer work?

A.  The balancer works with both inline and pancake motors. The motor spins almost on air between the two magnets on the tip of the adjusting screws. Instructions on how to balance armatures are supplied with each unit that is purchased.
The motor is placed between the two magnets on the adjusting screws. The motor will always be in contact with either the left or the right side magnet. The two vertical screws are used to lock the horizontal screws one side at a time. Once the first side is locked, the second horizontal screw is then adjusted to almost touch the armature shaft. See details below.

Q.  Does the Balancer have to be level in order to balance the motors?

A.   No. The motor can be balanced regardless of the orientation of the balancer.

Q.  Can the Balancer balance motors with damaged shafts?

A.   Yes, Not only can it balance motors with damaged shafts, but also motors that are magnetized, however you will need 
     to purchase the Enabler Tool to do this. See website under Balancer.


VRP COMM POLISHER SET

Q.  Why do you need a Comm. Polisher?

A.  The comm. polisher flattens the commutator after it is polished causing the brushes to have less movement while the motor is running. Less bounce equals more speed, more bounce equals less speed.  Less bounce equals more time in contact with the commutator plate. The result is that the motor runs faster because it gets more electricity.

Q.  How many motors can one disk do.

A.  The Course disks can normally do about 10 motors.
