Question 1

Is this sine waveform output to drive a motor? I mean that is it okay without connect the Hall inputs because the brushless motor doesnot output Hall?

Accepted Answer

It's not Sine output, it is switched DC 3 phase.

Question 2

Can i use this for a hover board bldc motor? it has 5 wires for the hall sensor, where do those go? hu, hv, hw, gnd, and +10v?

Accepted Answer

those wires connect to the speed controller, the wires show the controller the position of the rotor so it knows how much power to put on each phase, if you didn't buy the speed controller with the motor you should get it or it will not run the way you want it to.

Question 3

what is the input voltage?

Accepted Answer

Dear Customer 
Hope these information helps you

Rated voltage: 20 to 50 VDC
Rated current: 12A
Current limiting: 15A
Maximum speed: 20000RPM( the specific speed depends on the motor itself and load)
Usage environment: Avoid direct contact with dust, fumes and corrosive gases

USE Detail:
1.Two modes of speed regulation:
External potentiometer: through this potentiometer speed regulation;
External voltage: external 10VDC voltage speed regulation;
Note: The two speed regulation can not be used simultaneously

2. Speed output PG signal: There is a 5v-revolution pulse output between the port and the ground.
The output frequency is set to P (Hz), the motor class logarithm is N, and the speed is F (RPM), then the output speed frequency is P=F*N/60.
3. Alarm output ALM signal:There is an 5V alarm pulse output between the port and the ground.
4. Positive inversion function:

F/R:Fiddle the toggle switch on the corresponding side, the motor steering direction can be changed. For the toggle switch, the white part is up and down, then twang it up and down. For the toggle switch, the white part is horizontal, and the twang horizontally.
5. Start-stop (two control modes):
1. External switch EN: Transfer through switch.
2. Side toggle switch EN: for the toggle switch, the white part is up and down, then down for the start; for the toggle switch, the white part is horizontal, then dial to start
Note: You can only turn one control at the same time, one of the switches is closed, and the other one is valid.

6. Locked-rotor protection:If the motor stops working, switch on the power again to start.
7. Power light: Green light: power on and off
8. Status light: Red light: two flashes in standby time, after starting, extinguish. 
9. Insulation resistance: >100M at ambient temperature and atmospheric pressure
10. Insulation strength: At normal temperature and pressure, 0.5KV, 1 minutes

WS55-220 is a high performance,cost-effective 3 phase BLDC motor controller.Voltage range is from 20VDC to 50VDC.

This controller can be used in small equipment, Electric Power Tools, exhaust Fan, Jade grinding machine, Vibrating motor etc.
With overvoltage protection, over-current protection, locked-rotor protection.

Have a nice day,friend
Best Regards

Question 4

Can i use this on a motor without hall?

Accepted Answer

Yes you can. I have used them on a number of simple motors such as string trimmer motors.
