Why Choose Dunker Motors?

Why do we recommend selecting a sliding door operator equipped with a Dunker Motor? The answer lies, quite simply, in superior performance—delivering a smoother, more stable, and more reliable experience for daily use.

1. Operational Performance

As a German-engineered, industrial-grade motor, the Dunker Motor boasts exceptional operational precision. When integrated into our sliding door operators, it ensures reliable, long-term operation, effectively preventing issues such as vibration or misalignment.

2. Extended Service Life

Thanks to the high-quality design of this motor, OWNIC products exhibit outstanding wear resistance. They are ideally suited for high-frequency usage environments—such as the entrances of shopping malls and hospitals—and integrate seamlessly with our commercial and medical door product lines.

3. Low Failure Rate

The motor's inherent stability minimizes the maintenance frequency required for our 150 kg Automatic Sliding Door Operators, thereby reducing long-term operational costs.

4. Quiet and Smooth Operation

The sliding door operator operates with minimal noise, making it the perfect choice for environments with strict acoustic requirements—such as hospitals, office buildings, and other sensitive settings—where it can be deployed with complete confidence.

How to Install the 150 kg Automatic Sliding Operator with Dunker Motor?

I. Pre-Installation Inspection

Before installation, it is necessary to re-verify that the dimensions of the door opening align with the design specifications, that the weight of the door leaf does not exceed 150 kg, that the power supply meets the requirement for a stable AC 220V source, and that the wall or header structure possesses sufficient load-bearing capacity.

II. Standard Installation Steps

1. Rail Positioning and Leveling

First, drill the necessary holes and mount the rail; secure the aluminum alloy track to the door header beam. It is highly recommended to use an infrared leveler to ensure the track is perfectly horizontal; otherwise, the door leaf may drift or slide unintentionally due to the extremely low internal resistance of the Dunker motor.

2. Installation of the Drive Unit Components

Secure the Dunker motor assembly and the microcomputer controller to their designated positions within the track. Install the idler pulley (tail wheel) on the opposite end of the track, and route the power cables and sensor signal wires, leaving sufficient slack.

3. Installation of Door Leaf Hangers and Rollers

Attach the four-wheel hanger assemblies to the top edge of the glass door leaf. Then, suspend the door leaf from the track; adjust the anti-lift blocks on the hangers to ensure the rollers make firm contact with the stainless steel guide strips.

Install a floor guide on the ground to prevent the bottom edge of the door leaf from swaying.

4. Synchronous Belt Connection and Tension Adjustment

Use the connecting fasteners to secure the door leaf hanger assemblies to the synchronous belt. Adjust the tension of the belt using the adjustment bolt located on the idler pulley assembly until the belt is taut.

Given the powerful output of the Dunker motor, the belt tension should be neither too loose nor too tight.

5. Power-Up and Commissioning

Upon completion of the installation, perform a thorough cleaning to ensure that no metal shavings or debris remain inside the track.

Switch on the power supply. The controller will enter a self-learning mode, during which the door will execute one full open-and-close cycle at a reduced speed, automatically registering and memorizing the opening and closing limits (start and end points) as well as the weight of the door leaf.

FAQ

Q: Since this is a 150kg sliding door operator, can I mount a door leaf weighing exactly 150kg and use it continuously over the long term?

A: Yes, you can. This is because we utilize a Dunker motor in this sliding door operator.

While the service life of standard motors can be significantly shortened by prolonged operation under full load, Dunker motors are typically designed for a lifespan of 2 to 5 million open-close cycles. Even under a full load condition of 150kg, they maintain an exceptionally low failure rate.

Q: If a power outage occurs, will the Dunker motor generate significant resistance?

A: No, it will not. Although the motor is powerful, its internal electromagnetic design ensures that—in the event of a power failure—the motor's back-driving torque remains extremely low.

Pedestrians can easily push the door open manually, thereby meeting fire safety requirements.
