Rated voltage | No load speed | No load current | Rated torque | Rated speed | Load current | Starting current |
12V | 5000±10% | ＜8A | 0.47NM | 3700±10% | ＜25A | 110±10%A |
Test environment: Tested under a DC12V/50Hz regulated power supply, and compensated for voltage drop at the motor input terminal. The no-load speed of the motor is in a state without any load, and the average value is taken after running for 3 seconds.
Starting current: The rotor will exhibit different currents at different angles.
