automatic bearing door motor

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

Automatic bearing door motors are sophisticated pieces of equipment designed to provide smooth and efficient operation for various types of automatic doors. Here's a detailed introduction to these motors based on the provided search results:

Introduction

Automatic bearing door motors are the "brain" of an automatic door system, connecting with auxiliary equipment to control the opening and closing process of doors. They are crucial for the progress and perception of modern door systems, offering a high level of convenience and automation in various settings such as buildings, rooms, and vehicles.

Hardware Components

The hardware of an automatic door control system includes several key circuits:

• Power Circuit: Provides a stable supply environment, offering various voltages and currents to support the system.

• MCU Circuit: Utilizes a microcontroller, often a 16-bit DSPIC from Microchip, for high-performance motor control.

• Motor Driver Circuit: Comprises a three-phase driver IC and MOSFET from Infineon, capable of supporting over 240 watts of power.

• Sensors Circuit: Detects the current, speed, and position of the motor.

• Bus Circuit: Offers network communication via CAN-bus and RS485-bus, using Microchip’s MCP2551 for CAN-bus and MAXIM’s MAX13085 for RS-485.

Software Features

The software function of the automatic door control system includes door logical processing, motor control, network interface processing, and parameter sensing. The motor control is based on a fuzzy adaptive algorithm, which implements a three-loop controller of position, velocity, and current feedback.

Product Details

Specific models, such as the YF200, are brushless motors that provide power for automatic sliding doors with silent operation, high torque, long service life, and high efficiency. They integrate the motor with the gear box, offering strong driving, reliable operation, and increased power output, suitable for large doors. The helical gear transmission in the gear box ensures stable and reliable operation, even for heavy doors.

Specifications

For the YF200 model, the specifications include:

• Rated Voltage: 24V

• Rated Power: 100W

• No-load RPM: 2880 RPM

• Gear Ratio: 1:15

• Noise Level: ≤50dB

• Weight: 2.5KGS

• Protection Class: IP54

• Certificate: CE

• Lifetime: 3 million cycles, 10 years

Competitive Advantages

• Longer Life: Compared to commutated motors from other manufacturers.

• Low Detent Torques: For smooth operation.

• High Efficiency: For energy-saving performance.

• High Dynamic Acceleration: For quick response times.

• Good Regulation Characteristics: For precise control.

• High Power Density: Compact yet powerful.

• Robust Design: For durability.

• Low Moment of Inertia: For quick starts and stops.

In summary, automatic bearing door motors are advanced systems that combine hardware and software to control the operation of automatic doors. They offer a range of benefits, including silent operation, high efficiency, and long service life, making them an essential component in modern access control systems.
