Q: How about the noise level of your motor and do you have quiet motors?
A: Normally we define the noise level (dB) based on the back ground noise and measure distance. There are two kind noises: mechanical noise and electrical noise. For the former, it's related to the speed and motor parts. For the latter, it's mainly related to the sparks caused by the friction between the brushes and commutator. There is no quiet motor (without any noise) and only difference is the dB value.
Q: Do you have any subsidiary or agent here?
A: We don't have any subsidiary oversea except an agent in Iran (you can find the contact information via our sales engineer) but we will consider that in the future. We are always interested in cooperating with any worldwide company or individual who would be willing to be our local agents to serve our customers more closely and efficiently.
