Gate motor buying guide: sliding and swing gate automation

Updated November 2026. A gate motor turns a heavy manual gate into one that opens from a remote, a keypad or an access control reader. Choosing one is mostly a sizing exercise: gate type, gate weight, leaf length and how often the gate will run. This guide walks through each decision using the Nice gate automation kits and the ZKTeco sliding gate motor in our range. Prices shown are current catalogue prices including 18% GST.

Sliding or swing: start with the gate

A sliding gate runs along a floor track parallel to the boundary wall. The motor sits at one side and drives a pinion that engages a gear rack fixed along the gate. It needs side clearance equal to the opening but no space in front or behind, which suits plots where the gate opens straight onto a road or a sloping drive.

A swing gate opens like a door on hinges and needs clear space inside the arc of each leaf. Swing motors either mount on the surface, as an arm or telescopic ram between the pillar and the leaf, or sit in the ground below the hinge so the motor is hidden.

Size the motor by gate weight and leaf length

For sliding gates, total gate weight is the main sizing input. For swing gates, leaf length comes first and leaf weight second, because a longer leaf puts more leverage on the motor. A steel gate with cladding sheet can weigh far more than it looks, so work out the real figure and pick a motor rated comfortably above it: a rusty track, a dragging wheel or a solid leaf catching the wind all add load.

Sliding gate motors by stated capacity

Two more sliding options sit outside that table. The Nice RD400 kit (₹52,357) is a 24 VDC gearmotor with 400 N force and a built-in receiver, but our product data does not state its maximum gate weight, so check the datasheet against your gate. The ZKTeco ZK-SL700AC and ZK-SL1500AC Lite sliding gate motor is priced on request; its data lists 370 W and 450 W motor versions on AC 220V, IP55 protection and a gate speed of 11 to 13 m per minute, without a stated weight rating, so confirm the right version for your gate when you ask for a price. For heavy industrial gates on a 400 VAC supply, the Nice TUB4000 (₹273,760) lists 7740 N force and a built-in D-PRO 500 control unit.

Swing gate motors by leaf size

• Nice TOO3000: telescopic motor, 230 VAC, for leaves up to 3 metres and 300 kg, at ₹62,452.
• Nice TOO4500: telescopic motor, 230 VAC, for leaves up to 4.5 metres and 250 kg, at ₹75,284. Note the longer leaf comes with a lower weight limit.
• Nice TO5005: for swing gates with leaves up to 5 m, at ₹98,383.
• Nice TO4005 and TO4024: same 820 mm body and 1800 N force, one on 230 VAC (₹88,117) and one on 24 VDC (₹118,915).
• Hidden motors: the Nice LFAB4000 (500 Nm torque, IP67, LFABBOX4 foundation box) at ₹186,499 and the MFAB3000 (300 Nm torque, IP67, with connecting lever) at ₹166,824.

24 V DC vs 230 V AC

Both types connect to normal 230 V mains; the Nice 24 VDC kits list a 230 V input in their specs. The difference is the motor and control unit inside.

• 24 V DC motors typically give a soft start and slow-down at each end of travel and finer force control, and they suit busier gates. Compare the swing pair: the 24 VDC TO4024 is rated for 95 cycles per hour against 58 for the 230 VAC TO4005, with the same 1800 N force. DC systems can also run on a buffer battery during power cuts; the RD400, for example, has provision for the optional PSS124 buffer battery.
• 230 V AC motors are simple and robust and often cost less for a similar job, as the TO4005 at ₹88,117 against the TO4024 at ₹118,915 shows. Without battery backup, the gate must be released by hand during a power cut.

Most of the Nice kits are listed as non-reversible. A non-reversible motor holds the gate shut on its own gearing, so you do not need a separate gate lock, but it also means you use the manual release to move the gate when there is no power.

Duty cycle: how often will the gate run?

Duty cycle is how many open and close cycles a motor can handle in an hour before it needs to cool. A bungalow gate opening a few times a day will not stress any motor here, but a society, factory or car park gate can run dozens of times an hour, and an undersized motor will overheat and stop.

Working cycles per hour from our product data: RD400 and LFAB4000 at 20, MFAB3000 at 30, RBS600 and RBS600HS at 40 (stated for a 4 m leaf), RUN2500 and TUB4000 at 42, RB1000 at 50, TO4005 at 58, RUN1200HS at 60 and TO4024 at 95. The ZKTeco sliding gate motor lists an S2 working duty of 20 minutes and an MCBF of 1 million cycles.

Limit switches and encoders

The control unit has to know where the gate is so it can stop at fully open and fully closed. There are three common ways this is done:

• Mechanical or electromechanical limit switches: a cam or striker on the gate trips a switch at each end. Listed on the RB1000, RUN1200HS and RUN2500, and as an option on the ZKTeco motor.
• Magnetic limit switches: magnets on the rack trigger a sensor with no physical contact, so there is less wear and less trouble from dust. Listed on the RBS600 and RBS600HS.
• Encoders: the TO4024 has a magnetic encoder that tracks motor movement throughout travel, which lets the controller slow the gate near the ends and notice when it meets resistance.

Flashing light and safety accessories

An automatic gate moves a heavy load near people and vehicles, so safety accessories are essential. Several Nice kits come in two versions, and the flashing light version costs only a little more:

• RBS600 with flashing light at ₹66,558 against ₹63,991 without.
• RB1000 with flashing light at ₹89,485 against ₹86,833 without.
• RD400 at ₹54,495 with flashing light against ₹52,357 without, and RO600KCE at ₹63,649 against ₹61,083.

Beyond the flashing light, the compatibility lists for these kits name Nice photocells (EPS, EPM and EPL, plus BlueBUS and wireless versions), F210 and FT210 units for sensitive edges, and the ELAC and ELDC flashing lights: the 230 VAC TO4005 lists the ELAC, while the 24 VDC TO4024 lists the ELDC. Fit at least one pair of photocells across the opening so the gate stops or reverses if a car or person is in its path. You will find these in our sensors and safety devices category.

Remotes and app control

The Nice kits list 433.92 MHz transmitters from the ERA INTI and ERA ONE / MYGO families as compatible. Choose the channel count by what you want to control: two channels for the gate plus a pedestrian or partial opening, four if one remote should also run a second gate or a garage door.

• Nice MYGO2BD: 2 channels, bidirectional, range up to 200 m outdoors and 35 m indoors, battery life of 3 years at 10 presses a day, at ₹4,278.
• Nice MYGO4: 4 channels at ₹4,449.
• Nice INTI2: 2 channels at ₹3,593.
• Nice ON2E: 2 channels with rolling code at ₹3,764, though its data notes it is soon to be discontinued.
• Nice FLO2RE and FLO4RE transmitters (₹3,593 and ₹4,106): confirm they match the receiver in your kit before ordering.
• Nice BIDI-WIFI: a plug-in Wi-Fi interface that connects to the motor’s Bus-T4 connector, at ₹6,331.

The ZKTeco sliding gate motor uses a 433.92 MHz remote with a range of at least 30 m, and stores 20 remotes on the standard control board or 40 on the intelligent board.
