Neodymium Permanent Magnets 20170220
N35H NdFeB Neodymium Magnets for E-rickshaw Motor

Look for Neodymium Magnets for E-rickshaw Motor:
 

We are a leading manufacturer of mixer motor, and we are in process of manufacturing feasibility of E-rickshaw motor.
For which we have required the permanent magnet
Material: neodymium magnet 
Finish: Nickel coating
Field strength: 1800 gauss minimum

NdFeB Magnets Manufacturer China Rare Earth Magnet Limited:
We specialized in producing neodymium iron boron magnets.
Could you please inform us the grade?
If you could not figure out the magnets, please advise the attracting force and working temperature.
We will choose a grade accordingly for your reference.

Permanent Magnet Application    and Working Temperature:
I can tell you application.
It is used in the E-rickshaw motor (a public transport running on 48v battery carries 4-6 people)
Its temperature maybe 65-70°C, but this is a rough calculation because Environment Temp.  45-48°C is max in Summer time.
For the grade you have better suggest.
And what is the life of magnet as per the mentioned Temp. range?
Please submit the specification of magnet including life test/parameter test.

Neodymium Permanent Magnet Manufacturer   China Rare Earth Magnet Limited:
If the magnets are not used in harsh and severe environments, such as in water or acid environment, they can be used for several decades.
Attach is the specification of N35H, but we do not have life test.
If you need test report of dimension and demagnetized curve, we will provide such documents after production.
