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

A mobile robot carries its own power station, and every part of its drive train has to live with that fact. Servo motors designed for a mains-fed machine cabinet assume a supply that a battery-powered chassis does not have. The Kinco Driver / Motor (SMC60S-0040-30QAK-5BSU) is built for the battery side of that divide: a 400 W low-voltage brushless servo motor on a 60 mm flange, rated 3,000 rpm at 48 V DC. It is sized for the DC bus that automated guided vehicles, autonomous mobile robots and compact automation cells already run on, so the motor fits the vehicle rather than the vehicle being adapted to the motor.

Robots Europa, based in Dublin, supplies the SMC60S-0040-30QAK-5BSU to robot builders, system integrators and maintenance teams across the European Union and the DACH region. Robots Europa prepares each quotation around the project in question, agrees the exact variant with the customer before an order is placed, and arranges delivery and after-sales support from its European base.

Background

Kinco and the SMC60S series

Kinco is an industrial automation brand whose catalogue covers motion control together with the controllers and drives that surround it. Its servo motors are found in machine building and in mobile robotics, where low-voltage designs are paired with matching drives on a battery bus. The SMC60S series is the small-frame, small-inertia branch of that family: a range of low-voltage brushless servo motors that share the 60 mm flange. The sources name several codes within the series — 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 letters distinguish their configurations, and the figures on this page belong to the QAK-5BSU version alone; the other codes are not given its ratings, and it is not given theirs.

Low voltage, brushless and sealed

Three design decisions define this motor. The first is the 48 V DC rating, which places it on the same supply level as the traction batteries common in mobile robots and lets integrators avoid a high-voltage stage on the vehicle. The second is the brushless construction: commutation is handled electronically by the drive, so there are no brushes to wear, no brush dust inside the housing and no brush replacement in the service schedule. The third is the enclosure. The motor is totally enclosed and non-ventilated, with an IP65 body and an IP54 shaft seal, and its windings carry class F insulation. A sealed, fanless housing suits robots that work in warehouses, production halls and loading areas, where dust and occasional splashes are part of the daily environment and an air intake would be a liability.

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; Robots Europa confirms each of these at quotation.

What do the peak torque and peak current ratings mean for a robot drive?

The SMC60S-0040-30QAK-5BSU is rated for 1.27 N·m of continuous torque and 3.81 N·m at peak, three times the continuous figure, with a matching pair of current ratings: 10.1 A rated and 30.3 A peak. For a robot this gap is where much of the real work happens. A loaded vehicle starting from rest, a platform climbing a ramp at a dock door, or a lifting axis breaking a load free all ask for short bursts of torque well above what the motor delivers hour after hour. A motor with a generous peak rating can handle those moments without being oversized for the steady cruising that makes up most of a shift.

The standstill rating matters as well. At 1.40 N·m, the rated standstill torque is the figure that governs holding a position under load — keeping a vehicle steady on a slope or a lift at height while the drive holds the shaft. On the speed side, the motor is rated at 3000 rpm and reaches a maximum of 3500 rpm, which leaves headroom above the rated point for travel moves where speed matters more than torque. The drive selected for this motor has to be able to supply the peak current, and that pairing is one of the first points Robots Europa looks at with each enquiry.

Why choose a 48 V DC servo motor rather than a mains-voltage one?

On a fixed machine, a mains-voltage servo is the natural choice because the cabinet already has the supply. On a vehicle the situation is reversed. A battery pack delivers low-voltage DC, and every conversion stage between battery and motor adds weight, heat, cost and another component to certify. A motor rated for a 48 V DC link connects to the battery bus through a low-voltage servo drive, keeping the electrical architecture short and the energy path direct. Low-voltage systems also simplify certain aspects of electrical safety and service work, which is why they have become the norm in mobile robots and automated guided vehicles built for European sites with CE marking in mind.

The motor does not work on its own: it is one half of a drive pair, and the servo drive chosen alongside it shapes how the axis behaves. Robots Europa also lists other Kinco items, such as the Kinco Driver / Motor (FD124S-CB-005) and the Kinco Driver / Motor (FD134S-CB-000), which can be discussed as part of the same enquiry.

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

The clearest audience is the builder of battery-powered vehicles. Teams developing autonomous mobile robots, tuggers and automated guided vehicles for warehouses and distribution centres — the kind of machines found among Logistics Robots — need compact traction and lifting motors that run directly from a 48 V DC bus, and a sealed small-frame motor fits that brief.

Machine builders and integrators working on production equipment are a second group. Low-voltage servo motors appear in compact handling cells, conveyor modules and small axes alongside the equipment described under Factory Robots, particularly where a machine already carries a DC supply or where low voltage simplifies the design.

A third group is maintenance and fleet operators. Where robots built with SMC60S motors are already in service, a spare of the exact code keeps the fleet running without redesign; Robots Europa matches the code letter by letter so that a replacement corresponds to the motor it replaces. Research and development teams prototyping new vehicles form the fourth group. Projects whose requirements point towards a different frame or rating can compare another Kinco motor listing, the Kinco Driver / Motor (SMC80S-0075-30MAK-5DSU).

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

1. Wheel drives on autonomous mobile robots: traction from a 48 V DC battery bus in a compact sealed housing.
2. Automated guided vehicle traction: steady torque for continuous travel with peak reserve for starts and ramps.
3. Lifting and jacking units: raising shelves, carts or pallets on top-module robots, with standstill torque for holding.
4. Conveyor and roller top modules: driving transfer units on vehicles that hand over loads at stations.
5. Compact automation axes: small linear or rotary axes in handling cells that run on a DC supply.
6. Fleet spares and replacement: exchanging a motor of the same code in robots already in service.
