What are the selection criteria for the gear motor program

2021-04-16 15:24:50   |  What are the selection criteria for the gear motor program

  Gear motors make these movements possible: fast, precise, continuous, with or without shifting, etc. All of these should have corresponding gear motor technology that meets specific standards.

What are the selection criteria for the gear motor program

  1. You have to choose among four main motor types:

  AC general purpose motor (single-phase or three-phase)

  Brushed DC motor (permanent magnet DC)

  Brushless DC motor (abbreviated as BLDC, using electronic commutation)

  Gearbox motor (AC/DC/BLDC motor and gearbox organic combination)

  2. What application types are suitable for the above four main types of gear motors?

  For applications that run continuously and rarely change gears, an AC general-purpose motor is a better choice.

  For discontinuous dynamic applications, then a brushed DC motor or a brushless DC motor is the ideal choice.

  For low-speed and high-load applications, a gearbox with a specific reduction ratio in AC/DC/BLDC motors is an inevitable choice.

  For applications that require precise control of speed and/or torque, then you need to add a corresponding encoder to the AC/DC/BLDC motor (feed back corresponding data for precise control).

  For applications that require precise positioning, stepper motors are a better choice.

  3. According to different sports needs, it is also necessary to determine the technical specifications and dimensions of the motor:

  In order to determine the technical specifications, the power, torque and speed of the motor need to be determined first.

  In order to determine the size, you must know the size of the motor and how to install it (how to fix it in the system).

  When choosing the size and robustness of the motor, the industrial environment in which the motor works must also be considered: each environment (explosion, humidity, corrosion, high and low temperature, etc.) has a different design.

  For harsh environments, it is necessary to add a waterproof, dust-proof and shock-proof enclosure to the motor.

  4. In recent years, the energy efficiency of motors has also become an important factor in motor selection:

  The higher the energy efficiency of the motor, the more energy-saving the corresponding product, which can help customers improve the competitive advantage of the product in the market.

What are the advantages of planetary gear motors
READ MORE

The two biggest advantages of planetary gear motors are high power density, compact size and weight. Planetary gear motors are usually quite efficient, usually highly accurate, and have almost no recoil compared to other gear types. On the other hand, the cost of planetary gear motors is often slightly higher than other types of configurations, and the design is more complicated.

What is a planetary gear motor? In engineering projects, considering the design specifications, required performance or space constraints, different types of gear motors are required to complete the corresponding transmission. Gear motors include different gear types. Common types include spur gears, worm gears, helical gears, planetary gears, and even harmonic gears. The common type used with DC motors is planetary gear motors.
