OEM Motor Drive Capabilities | Design, Standards & Manufacturing

Versa Drives’ core business is to design and manufacture motor drives customised to the application. Across more than three decades, we have built experience controlling most motor types up to about 20 HP (≈ 15 kW), while designing to international industry standards wherever required.

Because we own both design and manufacturing, we can select the right motor and control topology, design the power electronics and embedded firmware around it, and deliver a production-ready controller or motor–drive set that fits the OEM’s product and duty cycle. Our embedded-systems experience also allows us to integrate PLC-like logic and application functions into the drive, reducing the need for separate controllers in many machines.

Drive Capability Ranges

Input Supply	110 V AC, single-phase 230 V AC, single-phase or three-phase 415 V AC, three-phase 90–265 V AC universal-input front ends 12 V DC to 800 V DC buses for low- and high-voltage DC systems
Output Power	230 V, three-phase drives up to approx. 5 HP (3.7 kW) 415 V, three-phase drives up to approx. 20 HP (15 kW) Low-voltage DC drives for 12 / 24 / 48 / 60 / 72 V systems in the sub-kW to few-kW range
Safety & Electrical Standards (Design Experience)	Safety frameworks: UL / CSA / CE Electrical & EMC: EN / IEC 61000 family CISPR 11 / 22 EMI/EMC management with appropriate filters, chokes and PCB layout rules
Interfaces & Communications	Digital I/O for commands, status and interlocks Analogue inputs for speed/torque reference and sensor feedback Encoder interfaces for incremental encoders Communication interfaces: MODBUS, RS-232, RS-485 CAN for EV and industrial applications Options for Bluetooth or Wi-Fi modules where end products require connectivity
Special Functions Implemented in Projects	Power factor control where required Electronic gearing and synchronisation Braking (dynamic or regenerative depending on system) DC operation for battery and DC-bus systems Dual-output drives in some applications Fanless designs for low-noise / high-reliability needs Maximum Power Point Tracking (MPPT) for solar pump controllers
Enclosures	Designs from open-frame electronics to IP20–IP66 enclosures Integration into OEM housings when the drive PCB is part of the machine assembly

Manufacturing Infrastructure & Capacity

Production Capability

Single-shift capacity of 100,000+ drives and around 200,000 fans per year, with room to scale
Most components and sub-assemblies sourced and produced locally, with suppliers developed over two decades

In-house Assembly

PCB assemblies built in-house on automatic and semi-automatic lines
Drive assemblies tested under defined procedures for each product family
Roadmap for further automation of assembly lines

Supply-Chain Strength

Long-term relationships with semiconductor manufacturers and global distributors
Ability to balance performance, cost and availability while managing supply risk

Footprint

Production space: approx. 450 m² (4,800 sq.ft.)
Stores / warehousing: approx. 450 m² (4,800 sq.ft.)

This combination of in-house PCB assembly, local mechanical supply and strong semiconductor partnerships allows Versa Drives to support both long-running volume products and specialised, lower-volume OEM controllers.
