Are things moving when they should stay still? Does your bed, desk, lift or machine creep or drift when you turn off the motor? That’s backdriving! Many people use doğrusal aktüatörler every day. You press a button. The actuator moves. It makes things go up, down, out, or in. But sometimes, when force is put on your actuator, it starts to move backwards even though it’s supposed to hold still. This problem is called backdriving. Let’s learn how to stop it, keep safe, and pick the right actuator with help from Jimi Technology!

Why Do We Need To Prevent Backdriving?

Imagine a patient lift going down by itself. A big solar panel changing angle with the wind. A robot dropping a part. Scary, right? Bad things happen:

• Safety hazards: People can get hurt.
• Loss of position: Things end up in the wrong spot.
• Equipment damage: Pieces break or motors burn out.
• Wasted energy: Drifting chews up power.
• Downtime: Machines stop, slowing work.

You need actuators that hold their place and keep everything safe. At Jimi, we’re experts at making sure your machines stay put—no matter what.

What Makes Backdriving Happen?

Backdriving sneaks up for lots of reasons. Here are the big ones:

• Ball screws: Fast, smooth, but easy to backdrive.
• Lead screws (Acme/trapezoidal): Slower, rougher, often self-locking.
• Worm gears: Most are self-locking. The load stays where it should.
• Gearbox type and ratio: Some hold firm, others let things slip.
• External load: Heavy weights can overcome the actuator’s holding strength.
• Vibration or shock: Sudden bumps can break static friction.
• Lubrication and wear: Grease and age can make parts slip.
• Motor holding torque: Some motors don’t keep things still when power is off.

How Do Linear Actuators Work?

It’s easy. You press a button. Electric energy turns to doğrusal hareket—things move up, down, in or out. Actuators have:

• Lead screws veya bilyalı vidalar for changing spinning to sliding.
• Gearboxes to change speed and force.
• Brakes Ve clutches to stop or hold.

But if force turns the screw or gear the wrong way, you get backdriving.

At Jimi, our team of engineers knows just how to design actuators so you don’t have to worry.

How Can We Stop Backdriving?

Here’s how the experts at Jimi keep things safe:

1. Use Self-Locking Mechanisms

• Worm gears: Gears shaped like screws are hard to backdrive.
• Self-locking lead screws: Special threads don’t let forces turn the screw.

2. Add Brakes

• Power-off brakes: These lock when the power goes out for safety.
• Dynamic braking: The motor slows fast and holds still.
• External brakes: Extra clamps or pads for strong hold.

3. Use Clutches

• Overrunning clutch: Lets motion in one way only.
• Locking clutch: Engages for full stop.

4. Mechanical Locks

• Pins, clamps, wedges: Make things stay; used for backup.

5. Choose The Right Motor

• Step motorlar: Hold position well.
• Servo motorlar: Can have built-in brakes or codes to stay put.

6. Gear Ratios

• High ratio gears: Make it much harder for force to turn things back.

7. Load Management

• Right-size actuator: Pick an actuator that can handle the weight—always!

Picking An Actuator That Won’t Backdrive

When you choose an actuator, think about:

• Load Type: Vertical, inclined, heavy, or precise.
• Görev Döngüsü: How much will it run? Will it sit still a lot?
• Çevre: Is it hot, cold, wet, or dusty?
• Safety Needs: Medical, people-lifting, robots, solar trackers.

Always read the manufacturer’s specs, or better yet—talk to the experts at Jimi. We’ll help you choose and even customize to your needs.

How Do You Test An Actuator For Backdriving?

Testing is very important!

• Load testing: Put big weights on it, see if it slips.
• Simulate power failure: Turn off the juice—does it move?
• Long-term stability: Check after thousands of cycles.

Jimi’s actuators are tested to strict global standards. Our labs use load, vibration, temperature, and cycle testing. Our products pass with flying colors!
