Solve the problem of excessive sparking brush dc motor controller

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.
