How to adjust the rotation speed of DC gear motors?

VEER Motor focus on the R&D and production of right-angle reduction gear motor for more than 12 years, with rich experience.

  1. The rotation speed of DC gear motor can be adjusted by yourself. If the gear motor is not DC gear motor, which the rotation speed can be adjusted by DC supply power with adjustable voltage function. The voltage of supply power high or low will affect the rotation speed of DC gear motor.
  2. There are different of reduction speed with adjustment speed of DC gear motor. Adjusting rotation speed, which is changing the voltage of supply power or changing the parameters of drive circuit of DC motor, then to achieve the purpose of adjusting the rotation speed. But for reduction speed (in most cases), which is installed a gearbox with some gear ratio on the end of output shaft of motor, then to reduce the rotation speed, but at the same time increase torque.
  3. DC motor is divided into brush motor and brushless motor, the former can be adjusted by changing the voltage of supply power; the voltage of the latter supply must be constant, and the rotation speed is adjusted by driver.
  4. There are two kinds of drivers of brushless DC motor: built-in and built-out. For built-in type, which cannot be adjusted the rotation speed, but the rotation speed of built-out type can be adjusted or not, which depends on the internal structure of drive.
  5. Magnetic DC motor is brush motor mostly. If rated operational voltage is 12v, you can use the 0~12v of DC stabilized power supply to power, and then the motor can be adjusted speed in stepless situation.
The run-in period of DC gear motor is very important, so VEER Motor advises our customers carefully take care of your DC gear motor

How to pass run-in period of DC gear motor safely?

The new DC gear motor is manufactured from factory, which usually needs to pass the run-in period before using. The operation of gear motor during the run-in period has an important impact on the later use. Therefore, we should use the motor in the correct way during the run-in period to ensure that it can safely pass the run-in period.

  1. Choose lubricating oil reasonably, especially for dc motor with input power greater than 11KW, which load gear oil should be injected.
  2. At ordinary times, pay more attention to check the lubricating oil, hydraulic oil coolant, and keep the oil level and quality in good, pay attention to check the sealing of the whole gear motor. If too much oil is lost during inspection, which the reason should be analyzed. At the same time, the lubrication of each lubrication point should be strengthened. It is suggested to add grease to the lubrication point every week during the run-in period (except for special requirements).
  3. To keep the gear motor is clean, adjust the loose fastening parts of gear motor in time, to prevent the looseness of DC gear motor cause by the wear out of parts or causing the loss of parts.
  4. At the end of the run-in period, the motor should be maintained compulsive-check and adjusting, and pay attention to the replacement of lubricating oil.

In conclusion, the run-in period of DC gear motor is very important, so VEER Motor advises our customers carefully take care of your DC gear motor. Any maintaining questions of gear motor, just contact us freely.
