Sabvoton Sinewave Controller

Instructions for Sabvoton Sinewave Controller

   Sabvoton Sinewave Controllers are electric scooter / electric motorcycle grade sinewave controllers. They power and control 3-phase brushless motors and require hall sensor input. However they can be retrofitted to Electric Bicycles and when paired to a suitable motor, can give very powerful acceleration and top speed. I recommend the SVMC72150 version, which is capable of 150A battery and 350A phase. Which is @74V 11100W Battery and 25900W Phase before taking into account resistance and losses. This is a very capable Sinewave Controller and has been track tested.

Getting Started With Sabvoton Controllers

1. Phase / Hall Combos

These are the known Phase and Hall combos for the follow motors

Cromotor - Matching Phase and Hall Colors

MXUS 3000 - Swap Yellow and Green Phase - Swap Yellow and Green Halls

QS Motor - Matching Phase and Hall Colors

Cyclone 3000W - Phase all match - Swap Yellow and Green Halls

2. Wiring Diagram

 

Notes: Red and Black Wires are the battery wires.

1) Connect the orange E-lock wire directly to Red positive to start controller.

*2) If you have a power switch then connect the e-lock (orange wire) to one of the wires on the switch and the other wire from the switch to red positive.

Additionally: If you are using a Cycle Analyst with the shunt Adapter and a power switch then it would be like this.

 *Note a power switch is not required but is highly recommended

3. Download Software

2a. Install USB drivers, then install the Sabvoton Software

4. Programming the Controller

Connect the USB programming cable into the controller. The larger part of the cable plugs into the computer's USB port. Make sure controller has power.

 

Click Set>Port #

This varies depending on your computer, but generally try Ports 1-5 and see if your computer has communicate with the controller. You will know once the software interfaces with the controller.

Parameters

Basic

Lack Volt = Think of this as the low voltage cut off, set this to the minimum voltage you want the controller to cut off power.

Example: Your using a 48v battery, you want to set this around 42V

Over Volt = Over voltage protection, I would set this to 95v or slightly above your battery's maximum voltage. The maximum setting is 95v.

Example: Your using a 48V and you to set this around ~55v

Rated DC Current = This is the continuous rating for Battery amps, which dictates power. Set this Rated DC current = Max DC current or lower than Max DC Current. Increasing this number will increase wattage power and top speed.

Example: Rated DC Current 50A x 48V = 2400W!

Max DC Current = Maximum amount of Battery amps. Increasing this number will increase wattage power and top speed. But keep this equal to or higher than Rated DC Current.

Example: Rated DC Current 50A and Max DC Current 70A

Limit DC Current = Set this to match the Rated DC Current

Rated Phase Current = Phase amps, this controls the continuous amount of phase amps going into the motor. More phase amps will increase torque and acceleration. Generally you want this higher than Battery Amps, about 2-2.5x higher, but tune to your setup accordingly. 

Max Phase Current = The maximum amount of phase current, keep this equal to or higher than the Rated Phase Current.

Functions

 

Electric Brake = Enable for Regen, only applies to Direct Drive Hub Motors.

Flux Weakening = Enable to increase top speed at the expensive of efficiency.  Also known as field weakening. Do not recommend higher than 50A otherwise you can damage or destablize the motor's magnets.

Flux weakening current = 0-150A, the higher this setting the higher you can boost the top speed of your motor. Technically this counters EMF of the motor and forces the motor to run at a higher RPM.

Electric Brake Ph current = 0-200A This controls how strong the regen will be I generally set this at 100A on a 17" moto wheel for street riding and 150A for track riding. 26" Wheel you would want 80A or higher. Be warned, setting this too high will skid the rear tire upon deceleration and can fish tail the rear. Again, tune according to your motor and wheel setup.

Motor 

Pn = Very important to set the correct number of pole pairs for the motor otherwise you will have poor performance. This is the number of magnets in your motor divided by two.

Hall Angle Test = Very import to run the Hall Angle Test map the hall sensors with the controller. Gone are the days of trying various hall and phase combinations. 

Try a phase combo then click enable hall angle test, and change control mode to hall angle test. Click OK, then also change the test given current setting from 10A-28A, your motor should spin forward. Very Important to suspend the bike, because the motor will spin on its own for a few minutes. 

If Hall Status = Passed then congrats you found the right combination! The Hall Angle setting should have changed to the proper "degree". Click OK then yes on parameter store. Restart the controller and take it for a spin!

If the motor spins backwards change the Motor direction setting under "Motor"

If the Hall Test fails then change a different phase combination and run the hall test again.

To save the settings, you have to click SET! > DEBUG > Parameter Store > Yes and click OK.  That will save the settings.
