THE DM01 MOTOR: ENGINEERING EXCELLENCE FOR E-BIKES

Hello. In relation to the DM02 500w 52v, is that 500w continuous or 500w max? If continuous, what is the max current likely to be?

What gauge (amperage) power wires should I use from the battery to the controller?

What amperage fuse should I use?

Hello, thanks for your inquiry, sorry for the late response because of the Chinese New Year vacation.

Please note that our mid-drive motors are defined by a rated power, so the peak power of our 500W motor is greater than 500W. In our recommendation, the maximum current should be 20A for a 500W 36V, and 18A for a 500W 48V motor.

Typically, there is no need to insert a fuse between the battery and the controller. Because:

The battery itself has a maximum discharge limit.
The controller often includes built-in maximum current protection.

Any further questions you are welcome to reach out at any time.
 
Perhaps you can also answer some more details about the torque sensor itself:
1. is torque reading linear?
2. what is the maximum torque reading range?

How does Toseven's torque sensor differ in design from Tongsheng's TSDZ2? Can you give us an overview with photos and diagrams?

Happy New Year!

Happy New Year! Thanks for your inquiry; we kindly recommend you buy one of our mid-drive motors and test the difference between our DM motor and TSDZ2; thanks.
 
Hi Happy New years!

Are you saying you have to buy the motor to get answers about your products?

That's not even remotely a useful answer to the question:

I think y'all should hire some actual customer service and support people that can read questions and answer them usefully.

Hello, thanks for your inquiry! Please have our response as below:

1- yes, our torque is reading linear
2- the max. torque reading is 3.3v

Ad. 1. thanks, that is promising
Ad. 2. sorry i was not precise: what weight can be read when put on the pedal? like 40kg, 60kg ? or can you provide torque reading?
 
Since to7motor@SZ didn't answer my questions about the torque sensor, I searched and found this image on reddit
Can someone check it for accuracy?

It says the torque sensor is a strain resistance type. Looks like it's located external to the motor, unlike the TSDZ2 which use a wild scheme hall effect torque sensor via a transformer inside the motor casing. How well the Toseven torque sensor works remains to be seen.

He seems most confused by magnet placement on the rotor by not being surface mounted. I read something about "buried" magnets as in the ToSeven design. It's that way for a purpose, but I can't remember what. Something to do with how the magnetic field works in the motor.

Hi,
id also like more information on the To7 Torque sensor. I had a TSDZ2, the torque sensor failed twice within a week, got free repalcements via PSPower. It was a good motor when it worked, feeling good with Torque sensing, but i could not trust its relaibility to assist my cargobike which i used daily for school runs and work. It ended up on my wifes leisure bike, and i switched from a hefty Dutch Cargobike to a lightweight Bullitt, still manually ridden... :)
