DC motors are popular in door automation systems due to their ease of control. They are also energy efficient and offer a variety of speed and torque options.

  • AC Motors

    AC motors are also popular in door automation systems. They are divided into two types; induction and synchronous motors. They produce a high speed and constant torque, making them suitable for heavy doors. They also require low maintenance and offer high reliability. However, they need a specific speed control system, making them less versatile than DC motors.

  • Stepper Motors

    These are electric motors that move in discrete steps. They offer precise control over the door's opening and closing position. They are also suitable for applications that require accurate door automation. Due to their high precision and reliability, they require more complex control systems. They are also less common in automatic door systems.

  • Servo Motors

    These are motors that work with a feedback system. They provide high precision and smooth door movement. They are mostly used in automatic doors that require quick and quiet operations. They also offer variable speed and torque, making them suitable for different types of automatic doors.

  • Geared Motors

    These are motors with gears that increase the torque and reduce the speed. They are suitable for large and heavy doors. The geared motors are powerful and provide high lifting capacity. They are also very efficient. The motor's slow speed makes them ideal for applications where speed is not very important.

  • Magnetic Motors

    These are motors that use magnets to create motion. They are efficient and provide a high power-to-weight ratio. They are also quiet and have no internal friction, making them suitable for automatic doors in noise-sensitive areas.

Functions and features of door motor

Motorized doors are equipped with various functions and features that enhance convenience, security, and automation. Here are some key functions and features:
