Description:
This product is a driver module developed for non inductive BLDC motors. The main control chip for the driver is SNR8503M, which integrates a dedicated circuit for non inductive motor drivers. The chip has the characteristics of simple peripheral circuits, complete functions, small size, easy debugging, high driving efficiency, flexible application, and wide applicability.
The driver module measures 78x57mm in length and width, with a board thickness of 1.6mm and a working voltage of 6~80V. It supports anti reverse protection and will not damage the module due to reverse power line connection. The module defaults to a bare board. For motors with a driving current below 5A, forced heat dissipation is not required, only normal ventilation needs to be ensured. For motors with a driving current exceeding 5A, forced heat dissipation is required, and the provided heat sink can continue to operate at 20A current.
Applications: pumps, medical equipment, various compressors, various fans/fans, electric screwdrivers, electric curtains, automatic doors, hydraulic oil pumps, air pumps, refrigerator DC brushless compressors, lawn mowers, spray, underwater thrusters, etc.
