The driving principle of micro motor is analyzed
Source:本站 Author:常州方友机电有限公司 Release time:2023-3-24 15:08:12 Page view:424At present, the types of motor appliances are diverse, the demand for various styles of products on the market is also different, how is the micro motor driven, the micro electric push rod in the maintenance process what need to pay attention to? These are a piece of cake for motor manufacturers, but for users, there is no experience in this area, we will share one or two for you now.
The micro motor is generally driven by L298N, which can generally drive two motors at the same time, and two L298N can be used if you are worried about not enough drive. The internal principle is H-bridge differential amplification. L298N is a two-phase and four-phase motor driver, that is, a high-voltage and high-current dual full-bridge driver containing two H-bridges, receiving standard TTL logic level signals, can drive 46V, 2A and below the motor. The 1 and 15 pins of the micro motor can separately lead out the connected current sampling resistor to form the current sensing signal.
