What should be paid attention to when using permanent magnet DC reduction motor

1. Important considerations when using permanent magnet DC geared motors:

1. Low-speed, high-torque models require current limiting protection to prevent damage to the gear reducer due to stalling.

2. Instantaneous motor reversal generates significant current, which can affect motor life. Frequent reversals should be performed only when the motor is completely stopped.

3. If stalling is unavoidable during use, please inform us in advance so we can take necessary measures.

4. To mitigate interference signals when using a remote control, a 0.1uF (63V) capacitor can be soldered between the positive and negative terminals, with the negative terminal grounded.

5. The low stall torque of a permanent magnet DC motor is 5-6 times the rated torque. Stalling should be avoided as much as possible during installation, commissioning, and operation.

2. Important considerations when selecting a permanent magnet DC geared motor:

1. Before mass production, conduct prototype testing to confirm that the rated speed, rated torque, voltage, and current meet the requirements. If they are close, the motor is considered a reasonable choice and can be used. If the deviation is significant, the model must be replaced; otherwise, the service life and quality cannot be guaranteed.

2. The basic criteria for properly selecting a gear reducer motor are the rated voltage, rated speed, and rated torque.

3. The highest efficiency point in the performance indicators listed in the data sheet for each model refers to the rated speed and rated torque and is for reference only. The rated operating point of a gear reducer motor is a key factor in motor design. Operating near the rated point provides high efficiency and stable performance.

4. Under high deceleration and low speed conditions, refer to the allowable load and speed listed in the performance data sheet. Operating within these allowable load and speed conditions will shorten the reducer's service life or directly damage it.

3. Important points to note when installing a permanent magnet DC geared motor:

1. Do not forcefully strike the accessories mounted on the gear reducer output shaft to prevent excessive up and down movement. When installing a circular gearbox, control the length of the mounting screws; screwing the screws in too long can cause jamming of internal components.

2. Do not rotate the reducer directly at the output end, as this may damage the internal gears.

3. Before installation, perform a power-on test run to confirm that performance meets requirements before proceeding. Do not disassemble the reducer yourself to avoid affecting noise and quality.

4. Do not pull the leads hard enough, and avoid impacting or excessively bending the terminal, as this will result in poor internal conductivity.

5. Solder the motor wires before installation. Use a suitable soldering iron and solder, and be skilled, quick, and accurate. A 40W soldering iron with a tip temperature of approximately 320°C ± 20°C and a soldering time of 2-3 seconds is generally recommended. Prolonged soldering can cause internal desoldering within the motor, leading to poor electrical conductivity.
