Product Overview




Sabvoton Controller UnlockType SVMC 72150 V2 For 3000W 72V 150A Electric Spoke Hub Bicycle Motor

Sabvoton controller only design sine wave type controller so far, it’s brushless DC controller, 120 degree phase angle. Generally, we matched it well with QS Motor, if you want to match with new brand motor, some parameters should be tested by yourself.

P.S. If you have any confused about the shipping cost, please feel free to contact with us.  Also could place order but don't pay first, then we could adjust the price.


Unlock Type Controller SVMC72150 without Warranty, please noted and understand.

Btw., After unlock , controller svmc72150 battery current from 150A to 200A


One set including below kits

Product Description

A. Specification

1. SVMC72150 V1 sine wave motor controller




2. SVMC72150 V2 sine wave motor controller


Please Notes:

1). We have updated the 0-5v e-brake function.

Old: it should be press the brake switch then can achieve 0-5v e-brake function.

Update: you can achieve 0-5v e-brake function without press the brake switch.

2). For no lock type controller(higher amps), there is no warranty service. However we could offer our suggestions for you.

3). CA function not support this type, if want , please check links ( click here ). You also could customize the controller according to our provided drawing.

4). Pls. make sure all the connection is correct before power on. 5). This type of Svmc72150 does not support TFT speedometer. If equipped with TFT speedometer, you need to customize the wiring harness and communication,  click here . 


B. SVMC Controller List



1). There is no warrant for unlocked type controller and 96100 controller(even though normal type).

2). For SVMC 60A model, only support classic function.

3). Customized CA function not support anymore from May of 2017, but we will offer the drawing for you to guide how to connect with your CA display.

D. SVMC controller software interface


E. SVMC series wiring diagram

1. Orange ignition: the wire should be connected to battery positive.



2.1. H-brake: If the purple wire connect to 12V, the controller enter brake status, when it disconnect with 12V,the controller quit the brake status.



2.2. L- brake: If the Yellow wire connect to 0V(Battery negative), the motor stop running.

High brake wire connect with 12v brake wire of hand brake/foot brake; low brake wire connect with ground wire.

High brake and low brake cannot using in the same time.


3. Reverse:If the white wire connect to 0V(Battery negative), the controller enter reverse status, twist the throttle, the motor will spin in back direction. When the white wire disconnect with 0V, the controller quit the reverse status.



 4. 3 speed function


3 - speed mode(Button):


When select the 3 speed(button)in the software. use a button(which can be reset by itself) to connect the pink wire and ground wire.

Push it and release ,the speed gear will change according as follows:  3-2-1-2-3-2-1-2-3-……

When power on , the controller is in 3 gear mode (high speed mode).


3 speed (switch):


When select the 3 speed (switch) in the software.

Use such switch to realize the 3 speed(switch) mode.




If 3 speed (switch) mode selected,

a. Connect the pink and ground wire.

b. Enter high speed mode

c. Connect the transparent and ground wire. Enter low speed mode

d. Disconnect pink ,transparent wire and ground ,enter middle speed mode


5. 0-5v e-brake throttle:



Use a separate throttle to connect to the terminal above.

Please select the “ Ebrake-throttle ” mode, When spin the throttle ,the controller will enter the e-brake mode , the brake strength will follow the the throttle position. the max strength can be set from ” Electric brake phase current ” as following.





6. Motor temperature function.


The controller support KTY83-122 temperature sensor from motor inside. The function can be enabled or disabled from the software.


7. MQCON controller can be connected with computer by usb cable or connected with phone by blue-tooth, the computer interface is just same with the phone app interface.

Connect with computer

Before connected with computer ,please install usbdrive and volume software provided by the controller manufacturer


The usb cable should be connected in right way as the following picture showed:



For further information about “how to use computer to set the parameters”. Please ask seller for document “MQCON controller application user manual” and “ MQCON(Sabvoton) FOC Controller “Parameter Manual-EN ”


SVMC Blue-tooth Adapter

Also, the controller can communicate with the phone app.

In addition, for manual of “ how to use phone blue-thooth to set the parameters ”, please ask seller to get.


8.  Hall angle ---the most important parameter for MQCON controller.

Different type motor should use different angle in controller.

If use improper angle , the motor may not run in best status.

When the user does not know the “hall angle ”in advance , the user should get the paramenter by using automatic testing function in the software .

if the user know the parameter in advance ,just enter the right angle. For svmc series controller ,if used QS V1 or V2 type motor ,the hall angle is about 65. If use QS V3 type , the angle is about 250.

G. Additional notes:

1. All RTN pins are internally connected.

2. Meter function is to copy either of hall sensors.

3. Above pin definition is for classical type controller.

Pls. Contact with sales first if you don't know how to connect the controller with motor and other parts.
