Detailed Explanation Of Motor Selection Basis

Motor selection is to select motors with the best performance and cost-effectiveness according to the specific working conditions set to meet the needs of mechanical transmission or electrical control. Usually, multiple factors such as power, speed, voltage, load type, environmental conditions, working system and safety performance should be considered to determine the final selection plan.

一. Detailed explanation of motor selection basis

1. Power demand: The power of the motor should meet the maximum power required in its application. In theory, the motor should be selected to meet the maximum power while not being too large.

2. Speed realization: The speed of the motor should meet the operating speed requirements of the load to be driven. Usually, speed regulation needs to be considered, or a motor with a speed change device should be selected.

3. Load type: Select a suitable motor according to the type of load. For example, for equipment with large rotational inertia, a high-torque motor needs to be selected; other load types such as pipeline pumps and fans have corresponding selection requirements.

4. Environmental conditions: Motors under special conditions such as wading, humidity, corrosion, and flammability should be selected according to environmental conditions. For example, in corrosive media, anti-corrosion motors with stainless steel housings are often used.

5. Working system: Select appropriate motors according to the requirements of the working system, which are usually divided into long-term working system and periodic working system. The periodic working system should consider the number of starts, starting time, running time and load changes.

6. Safety performance: Select motors with appropriate protection levels according to the safety requirements of the workplace to ensure the safety and reliability of the working process.

二. Selection considerations

1. The selection index is not the higher the better, and it should be reasonably selected according to actual needs;

2. When selecting, the matching of the motor and the transmission device (such as reducer, coupling, etc.) should be considered;

3. Pay attention to choosing brands and manufacturers with complete specifications and reliable quality.

Motor selection is a complex process and needs to be reasonably selected according to specific working conditions. A detailed introduction is given from multiple factors such as power, speed, load type, environmental conditions, working system and safety performance.
