THE DM01 MOTOR: ENGINEERING EXCELLENCE FOR E-BIKES

[maxwolfie]

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!

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.

No, I am not buying one anytime soon. Here is someone ToSeven DM01 Set Up Questions who bought one and having problems setting it up. Maybe you can offer him some help?

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

https://www.reddit.com/r/ebikes/comments/17rqzmh

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.

A I ?

Likely as the answer cannot match the question.
