Kinco Driver / Motor (SMC60S-0040-30QAK-5BSU)

Keeping an axis turning is the easy part. The demanding moment comes when a loaded wheel, lift or slide must break away from rest, accelerate and stop again exactly on command, and that is where the margin between continuous and peak torque matters. The Kinco Driver / Motor (SMC60S-0040-30QAK-5BSU) is a 400 W low-voltage brushless servo motor on a 60 mm flange. It is rated at 1.27 N·m of continuous torque with 3.81 N·m available at peak, and it draws its power from a 48 V DC link rather than a mains-fed control cabinet.

Robots Middle East supplies the SMC60S-0040-30QAK-5BSU to robot builders, system integrators and automation teams across the Middle East. Our team prepares each quotation around your application, matches the motor and its accessories to your axis, and remains your point of contact for delivery and technical support once the order is placed.

Background

Kinco and the SMC60S family

Kinco is an automation manufacturer whose catalogue spans servo motors and drives, motion control and operator interfaces, and its components are widely used by machine builders and mobile robot developers. The SMC60S series groups compact low-voltage brushless servo motors that share the 60 mm frame. The sources name several versions with the SMC60S-0040-30 prefix: SMC60S-0040-30AAK-3LKH, SMC60S-0040-30ABK-3LKH, SMC60S-0040-30MAK-3DSU, SMC60S-0040-30MBK-3DSU and the SMC60S-0040-30QAK-5BSU described here. The suffix codes distinguish options within the family. Every figure on this page belongs to the SMC60S-0040-30QAK-5BSU alone and should not be read across to its siblings.

A small-inertia motor for DC-powered machines

The SMC60S-0040-30QAK-5BSU belongs to the small-inertia class. Motors of this kind are chosen where an axis must respond briskly to acceleration and deceleration commands, as with drive wheels, indexing mechanisms and short positioning moves, rather than where a heavy flywheel-like load needs smoothing. The motor is totally enclosed and non-ventilated, so it carries no fan and sheds heat through its frame. It uses three pole pairs, F-class insulation and a keyed shaft for a positive coupling to gearboxes, pulleys or wheel hubs. The low-voltage design is its defining trait: it is built for the battery packs and DC buses found in mobile robots and compact machines, where a mains-voltage servo would need conversion equipment that adds weight and complexity.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation.

The manufacturer has not published the weight, the length, the encoder type of this exact version, the rotor inertia, whether a brake is fitted, the cable connector details or the contents of the box; we confirm each of these with you at quotation.

Why choose a 48 V DC servo motor for a mobile robot?

A mobile robot carries its energy with it, so every component in the drive train is shaped by the battery. A servo motor rated for a 48 V DC link connects to the vehicle's own supply through a suitable drive, without the inverter stages needed to raise battery voltage to mains levels. That keeps the power path short, which matters on a chassis where space and weight are both scarce.

Low voltage has a consequence that designers must plan for: current. The SMC60S-0040-30QAK-5BSU is rated at 10.1 A continuously and 30.3 A at peak, so the servo drive, cabling, fusing and battery management system all need to be sized for those values. The peak figures are what the motor calls upon when a robot starts with a full load, climbs a ramp or brakes hard, and they are precisely the moments that decide whether a platform feels responsive or sluggish. With a rated speed of 3000 rpm and a maximum of 3500 rpm, the motor is normally paired with a reduction gearbox on wheel drives, trading speed for the torque needed at the wheel.

How well is the SMC60S-0040-30QAK-5BSU protected against dust and water?

The motor body carries an IP65 rating and the shaft seal an IP54 rating. In general terms, IP65 describes an enclosure that is dust-tight and protected against water jets, while IP54 describes protection against dust ingress sufficient to avoid harmful deposits, together with protection against splashing water. The shaft seal is usually the weaker point on any rotating machine, and the two ratings make that distinction explicit.

For warehouses, distribution centres and production floors where fine dust is part of daily operation, the enclosed, fanless construction is an advantage: there are no cooling openings to draw in contaminants. Where an axis is exposed to washdown or direct spray at the shaft end, the integrator should consider additional shielding at the coupling, and we are glad to discuss the installation environment as part of your quotation.

Who is the Kinco Driver / Motor (SMC60S-0040-30QAK-5BSU) for?

The first group is builders of autonomous mobile robots and automated guided vehicles, for whom a compact 48 V DC servo motor fits naturally into a battery-powered drive train. Projects of this kind are presented in our Logistics Robots category. The second group is integrators of factory automation who need a small, sealed motor for conveyor sections, positioning axes or auxiliary mechanisms on machines supplied from a DC bus; related systems appear under Factory Robots. The third group is research and development teams, universities and robot-building workshops that want an industrial-grade brushless servo motor for prototypes that may later move into production.

A servo motor needs a matching drive. Kinco drives such as the Kinco Driver / Motor (FD124S-CB-005) and the Kinco Driver / Motor (FD134S-CB-000) are listed separately, and our team will advise you on the right pairing for your axis. Where your axis calls for a different frame within the Kinco range, the Kinco Driver / Motor (SMC80S-0075-30MAK-5DSU) is also available for comparison.

What is the Kinco Driver / Motor (SMC60S-0040-30QAK-5BSU) used for?

1. Mobile robot drive wheels – propelling AMR and AGV chassis from the vehicle's 48 V DC supply through a reduction gearbox.
2. Lifting and jacking units – raising shelves, carts or pallets on top-lift robots, where peak torque covers the start of the lift.
3. Conveyor and roller modules – driving compact transfer sections on robots and stationary handling equipment.
4. Positioning axes – moving slides, turntables and indexing mechanisms that benefit from a small-inertia motor's quick response.
5. Automated carts and tuggers – powering battery-operated material transport in warehouses and production plants.
6. Robot development platforms – giving prototypes and educational robots an industrial brushless servo motor from the outset.

Frequently Asked Questions

What supply voltage does the SMC60S-0040-30QAK-5BSU require?

The motor is rated for a 48 V DC link, supplied through a compatible servo drive. It is therefore suited to battery-powered robots and machines with a low-voltage DC bus.

How much torque does the motor deliver?

The rated torque is 1.27 N·m (180 oz-in), the rated standstill torque is 1.40 N·m (198 oz-in) and the maximum peak torque is 3.81 N·m (540 oz-in).

What are the rated and maximum speeds?

The motor is rated at 3000 rpm and reaches a maximum speed of 3500 rpm. Most wheel and lift applications pair it with a gearbox to match these speeds to the load.

What flange and shaft does the motor have?

The motor uses a 60 mm (60 × 60 mm) flange and a keyed shaft. The key gives a positive, slip-free connection to gearboxes, pulleys and wheel hubs.

How is the motor cooled?

The motor is totally enclosed and non-ventilated, so it has no fan and dissipates heat through its frame. Its windings use insulation class F.

Can the motor be used in dusty environments?

The body is rated IP65 and the shaft seal IP54, and the enclosed, non-ventilated construction has no fan openings. Exposure at the shaft end should be reviewed for each installation.
