Our engineering group wants to use a small cross flow blower that has a brushless DC motor rated 24Vdc at only 1 amp. The blower assembly and motor does not have any safety agency approvals though it is built by a reputable motor company. Our company has a general rule that all motor devices must have UL, CSA and either TUV or VDE agency approval. Unfortunately, this blower assembly is not common and engineering cannot locate a compatible blower that has agency approvals.
Being that the blower motor is only 24Vdc at 1 amp and it is brushless, I assume the risk of fire is low. We could perform the locked rotor test and limit the input current. What other safety tests could be performed to adequately evaluate the use of this blower? Are there any safety standards specific to dc brushless motors? Would an NRTL require this kind of motor to have agency approvals?
