Shanghai STEP Electric Co., Ltd.
Shanghai STEP Electric began in 1995 with elevator serial control and subsequently developed industrial inverters, servo systems and robots. Its current manufacturing presentation distinguishes electrical equipment, motor and robot operations. For procurement, that breadth becomes useful when the task is defined precisely: a water-system drive, a dual-axis rotary servo, a direct-drive mechanism or a controller-and-I/O package each follows a different product route.

Elevator control explains STEP’s path into drives and motion
The current corporate timeline identifies product and manufacturing milestones across several distinct businesses.
- 1995
SmartCom and the original company
STEP records establishment on 10 March and release of its first elevator serial-control system, SmartCom.[1]
- 2004–2010
Drives, servos and public listing
The timeline records the iAStar S3 elevator drive in 2004, AS210 servo in 2006 and AS180/AS500/AS800 general inverters in 2009. In 2010 STEP listed in Shenzhen under code 002527 and introduced AS380 integrated elevator drive/control.[1]
- 2016–2022
Motion platforms and inverter development
STEP dates the Ω6 servo series to 2016, later SC motion-controller development to 2021, and the E6 intelligent flexible inverter platform to 2022.[1]
- 2025
Haier strategic investment
The present introduction records a strategic equity investment by Haier Group in June 2025, placing STEP within its industrial ecosystem. This is a corporate development milestone, separate from individual drive specifications.[1]
Three business fields
STEP’s current introduction distinguishes smart elevators, general automation and robotics. Its manufacturing and development history gives each a different context. A quotation should identify the actual equipment and supplying operation, whether it covers elevator control, an industrial motor or coordinated machine axes.[1]
Electrical cabinets, motors and robots have different production operations
The group overview names the manufacturing sites rather than treating the entire STEP portfolio as one factory line.
Electrical manufacturing and group operations
The Shanghai electrical factory is described as using a flexible elevator-control-cabinet production line with collaborative four- and six-axis robots. The overview separately names the Shanghai motor factory, Shanghai robot factory, cable operation, Hangzhou industrial-control company and Suzhou Xiao’ao operation. These references show why the production route should be established for the particular equipment being purchased.[1]
Research network and an external institutional record
STEP identifies research centres in Shanghai, Shenzhen, Xi’an, Hangzhou and Germany. The 2020 government enterprise technology-centre list separately names Shanghai STEP Electric’s technology centre at entry 373. That dated record corroborates the institutional research identity; model-level conformity documents remain part of the drive or system’s own technical package.[1][7]
The water-industry catalogue starts with the process, not just motor power
STEP groups dedicated inverters around HVAC, water supply, firefighting-related equipment and drainage applications.
The named dedicated families
The current catalogue lists AS560, board-drive products, D150, AS170 and S-series entries. This establishes an application-specific procurement route within the inverter business. The included controller functions, mains supply and exact motor rating should be obtained for the proposed model rather than borrowed from another family in the same list.[2]
Describe the pump system being controlled
For a water-supply enquiry, identify pump count, motor nameplates, pressure or flow feedback, duty/standby operation and existing controls. For HVAC, include the fan or pump operating sequence and plant-control interface. Those details allow the supplier to define what is in the drive and what remains in the external control system; regulated applications also require their project-specific control responsibilities to be established.[2]
The Ω6 catalogue separates single-axis, dual-axis and low-voltage routes
The current rotary-servo list provides distinct family choices alongside matched motors. Its family names should remain intact when comparing proposals.
Swipe horizontally to compare all columns.
| Current catalogue entry | Published role |
|---|---|
| Ω6-A | Flagship AC servo route |
| Ω6-C | Compact general-purpose AC servo |
| Ω6-W | One drive for two axes |
| Ω6-D | Low-voltage servo |
| Ω6-OMP | Servo motor family |
Different hardware boundaries
The dual-axis route changes amplifier count and cabinet layout, while the low-voltage route changes the supply architecture. The OMP entry names the motor side of the system. These distinctions are more useful than treating Ω6 as one electrical rating or assuming the same feedback and wiring on every offered model.[3]
Additional K1 and G3 products
The same catalogue lists K1 and G3 drives. K1’s description includes internal position planning with 32 data groups and configurable speed, acceleration and deceleration. Their presence broadens the motion offering, but the required function must be attached to the named drive rather than transferred across the full catalogue.[3]
Ω6-W brings two axes onto a common DC bus
The current product page describes a dual-axis AC servo arrangement for coordinated equipment, including gantry and other two-axis uses.
Common-bus architecture and feedback
STEP identifies a shared DC bus between the two axes and publishes a 3.0 kHz speed-loop bandwidth and 20-bit encoder description. A two-axis proposal should identify both motors, their torque cycles and the feedback arrangement together. The architecture alone does not establish the machine’s achieved synchronisation accuracy or energy reduction.[4]
Named machine applications
The Ω6-W page names 3C electronics, cutting, grinding and wire-bonding equipment. For a gantry, clarify the mechanics and coordinated-axis control; for other paired axes, identify how the two movements interact during acceleration, operation and stopping. Cabinet dimensions, braking behaviour and commissioning scope belong to the matched two-axis system.[4]
SC50 and SXE connect coordinated motion to the machine’s signals
The motion business includes the computing and field-I/O layers as well as servo amplifiers.
Controller, display and vision interaction
The current SC50 description identifies a quad-core Cortex-A55 architecture at 2 GHz and integrated display/control. STEP’s 19 December 2024 development report describes its Linux real-time platform and integration of motion, vision, AI and EtherCAT. The report names laser cutting, vision-guided dispensing and CNC as application areas. These describe the controller platform, not functions embedded in every inverter.[5][6]
SXE signal modules
The SXE bus-I/O description includes analogue voltage/current, digital I/O, temperature acquisition, pulse output/high-speed counting, serial communication and power-extension modules. A machine brief can therefore define which signals remain local, which use distributed I/O and which travel over the motion network. The controller, module list and drive interfaces should be specified together.[5]
Direct-drive mechanisms need their own definition
The motion overview separately identifies linear motors, direct-drive rotary motors, voice-coil motors and linear gantries. Their mechanics and feedback differ from a conventional rotary motor axis. Establish the actual mechanism and controller architecture before choosing between the direct-drive and rotary-servo product routes.[5]

Buyer questions
What is STEP’s original business?
STEP records its 1995 establishment and the SmartCom elevator serial-control system in its current corporate timeline.
What does Ω6-W add to the servo portfolio?
Its current product page describes one drive for two axes with a shared DC bus, alongside coordinated and gantry-type applications.
Does SC50 provide the same functions as an inverter?
No. SC50 is a controller/display platform described with motion, vision and EtherCAT integration. The inverter, servo and field-I/O functions belong to separately identified products.
