Today small make up take you to understand the causes of excessive sparking brush dc motor controller and processing method. 1. Reason: brush is not neutral line. Processing method: adjust the brush rod position, dispatch brush to neutral line. 2. Improper reason: brush pressure, or poor contact commutator. Methods: adjust the brush pressure, to be transferred to the appropriate location, or replace the commutator surface. 3. Reason: the commutator surface is not smooth. Methods: the commutator surface grinding. 4. Reason: motor overload or supply voltage is too high. Methods: to reduce the motor load and power supply voltage. 5. Reason: rotor dynamic balancing without correction. Processing method: for rotor dynamic balancing correction. These are the causes of excessive sparking brush dc motor controller and processing method, hope to help you use dc motor controller.
