Motorised Sliding Gate Installation Guide: Choosing the Right Motor Capacity for Residential and Industrial Use

A motorised sliding gate is only as good as the motor that drives it. Pick a motor that is too small and it overheats, strips gears and stops in the middle of the monsoon. Pick one far too big and you pay for power you never use. Whether you are automating a bungalow gate, a housing society entrance or a 15-metre factory gate, this guide explains how to choose the right motor capacity, which KT India motors fit each job, and how a proper installation is done.

The motor sits on a level plinth, and the rack is bolted along the gate so its teeth mesh with the motor's pinion.

KT India sliding gate motors by capacity

Step 1: work out the real gate weight

Motor capacity is rated by gate weight, so start there. Ask the fabricator for the weight, or estimate it from the steel used. A rough guide for Indian gates:

• Light MS pipe or grill gate, 4 to 5 m wide: 250 to 500 kg.
• MS sheet or box-section society gate, 6 to 8 m: 600 to 1,200 kg.
• Heavy industrial gate with sheet cladding, 8 to 12 m: 1,500 to 2,500 kg.
• Very large plant, port or warehouse gates: 3,000 kg and above.

Add a 25 to 30% safety margin. Wind load on solid sheet gates, dust in the track and wear on rollers make the gate harder to move over time. A 900 kg gate should get a 1,200 kg motor, not an 1,000 kg one.

Step 2: match the duty cycle to the traffic

Duty cycle is how long the motor can work without resting. A home gate opening 20 times a day is fine with a residential motor such as the Ditec ION 400, Ditec NEOS 600 or CAME 800. A society gate opening 200 times a day needs a heavier motor such as the NEOS 1000 or Mcvick 1200. A factory gate that opens for trucks all day needs an industrial motor with an oil-bath gearbox or 100% duty cycle: the FAAC 844 C Z16, the fast FAAC C851, or the 3-phase FAAC 844 R.

Step 3: choose the power supply and speed

• Single phase 230 V: most residential and commercial motors up to about 1,800 kg.
• Three phase 380-415 V: heavy industrial gates, using the FAAC 844 R 380 V operator or similar.
• Speed: about 10 to 12 m/min is standard; fast motors such as the 4,000 kg Mcvick (25 m/min) reduce queues at busy gates.
• Power cuts: every motor has a manual release key; ask about battery backup for critical gates.

Heavy factory gates need high-capacity motors with a high duty cycle, and safety sensors on both sides.

Installation guide, step by step

1. Check the gate: it must slide freely by hand on a straight, level track with good rollers and a top guide. A motor cannot fix a badly made gate.
2. Cast the plinth: a level concrete base inside the compound with the foundation plate and conduits for power and control cables.
3. Fix the motor on the plate, leaving room to adjust the height of the pinion.
4. Fit the gear rack along the gate, with a 1 to 2 mm gap above the pinion so the gate weight does not sit on the motor.
5. Set the limits: fit end stops and the limit switches, such as the Ditec magnetic limit switch, so the gate stops at the open and closed positions.
6. Wire safety devices: a safety photosensor across the opening (or a wireless photosensor where cabling is hard), and a loop detector for vehicles.
7. Commission the controller: set force, speed, soft stop and auto-close time, then pair remotes.
8. Test: confirm the gate reverses when the photosensor beam is broken or an obstacle is met, then hand over with a demonstration of the manual release.

Set limits, force and auto-close carefully at commissioning, and test that the gate reverses on an obstacle.

Signs a motor is undersized

If an existing gate motor hums but struggles to start, stops halfway, gets very hot after a few cycles, or needs the gate pushed by hand, it is probably too small for the gate or the track needs repair. Replacing it with a correctly sized motor is cheaper than repeatedly repairing a burnt winding or a stripped gearbox. Our technicians check the gate weight, track and rollers before recommending a replacement.

Recommended kit by site type

• Bungalow or villa: Ditec ION 400, NEOS 600, CAME 800 or Mcvick 600 with a photosensor and two remotes.
• Housing society: NEOS 1000, Mcvick 1200 or eSSL 1500 with photosensors, a loop detector and a guard push button.
• Office or commercial complex: Ditec CROSS18VEP, CAME 1800 or FAAC C851 integrated with access control.
• Factory or warehouse: Bennica 2000, CAME BK/BKE 2200, Mcvick 2400 or FAAC 844 R 3-phase.
• Heavy plant, port or logistics park: CAME 3500, Ditec CROSS35VEI, the Mcvick 4000 or the 4,500 kg motor.

Frequently asked questions

Can I automate my existing gate?
Usually yes, if it slides freely on a straight track. We survey it first and repair rollers or the track if needed.

What maintenance does a sliding gate motor need?
Clean the track, check rack alignment and rollers, test the safety sensors and the manual release every quarter.

Rack or chain drive?
Rack and pinion is standard for most gates; chain drives are used for some very long or heavy gates.

Will it work in rain?
Yes. Motors are IP-rated for outdoor use; keep the plinth above water level.
