Summary of the contracting process

The University of Edinburgh is procuring a non-torque loading system for testing electrical machines, including a drive system, installation and technical support. The equipment will apply controlled non-torque forces to the shaft or rotor of motors and generators, helping researchers study air-gap variation, electrical performance and mechanical integrity in machines for offshore renewable energy applications. It must support machines from approximately 0.5m diameter and 0.5m axial length to 1.0m diameter and 0.75m axial length, within a 5m by 2m enclosure and maximum 2m height. Delivery and installation are at the University of Edinburgh’s King’s Buildings in Edinburgh. This is a goods procurement, classified under CPV 31161000, and includes community benefit opportunities in Edinburgh and South East Scotland.

The procurement has reached tender: the University invited offers through an open procedure. Bids were to be submitted electronically by 28 September 2026 at 12:00, with public bid opening at the same time. The contract period is 720 days, with potential renewal for long-term servicing options. The single lot covers supply, installation and technical services or support. Evaluation is based on technical quality at 90% and price at 10%; variants are not allowed. Bids must remain valid for 120 days after the submission deadline and be submitted in English. The contract provides for electronic payment and ordering, with electronic invoicing permitted. The equipment must include a four-quadrant drive, force and torque measurement, motoring and generating modes, auxiliary systems and an external emergency-stop connection.

This opportunity suits specialist suppliers of electromechanical test rigs, dynamometers, motor-generator test equipment, industrial drives or structural loading systems. Competitors need to provide a complete operational installation capable of at least 20 kW, 20–100 rpm, 2,000 Nm at 100 rpm and around 50 kN force in the X and Y axes, with a 25 kNm moment about the vertical and horizontal axes. The preferred solution extends towards 50 kW or above, three-axis loading and speeds up to 10–1,000 rpm, with electrically actuated loading preferred. Suppliers must integrate load cells and torque measurement, support custom drive units, design the stator mounting solution and accommodate the specified floor construction. Capacity to install, commission and support complex research equipment is important, alongside credible servicing capability and useful community benefit proposals.

Notice Title

Non-Torque Loading System for Electrical Machine Testing Including Drive System

Notice Description

The University of Edinburgh seeks to acquire a Non-Torque Loading System with a minimum power rating of 20 kW and preferably up to 50 kW or above. The system should be capable of applying non-torque loads to the shaft/rotor of the motor/generator under test of at least 50 kN in at least 2-axes, but preferably 3-axes. It should also have a speed range of at least 20-100 rpm, but preferably up to 10-1000 rpm. Preference is for electrically actuated non-torque loading. Our researchers design, develop and test small electrical machines (at full scale), as well as downscaled prototypes of electrical machines for large offshore renewable energy applications.

Lot Information

Lot 1

The University of Edinburgh seeks to acquire a Non-Torque Loading System with a minimum power rating of 20 kW and preferably up to 50 kW or above. The system should be capable of applying non-torque loads to the shaft/rotor of the motor/generator under test of at least 50 kN in at least 2-axes, but preferably 3-axes. It should also have a speed range of at least 20-100 rpm, but preferably up to 10-1000 rpm. Preference is for electrically actuated non-torque loading. Bidders will be expected to work with the team at the university to design a mounting solution for the stator of the motor/generator under test. Our researchers design, develop and test small electrical machines (at full scale), as well as downscaled prototypes of electrical machines for large offshore renewable energy applications. To date, we have used an in-house drivetrain test rig, rated at 20kW and with variable speed capability up to 100rpm. This effectively means that we can control torque or rotational speed and the effective electrical load on the electrical machine under test. In our current and future work, we are interested in applying the non-torque loads that might be present in full scale environments to the electrical machines under test. In particular, we would like to understand how air-gaps of the electrical machine under test will vary when subjected to those non-torque loads, and hence impact on electrical performance and mechanical integrity. Ideally, this system would allow a complete electrical machine to be tested, without separation of and independent mounting of the rotor and stator of the electrical machine under test. Suppliers are invited to tender for the supply, installation, and technical services/support of this equipment. Minimum Technical Requirements: Dimensions: The system will be enclosed in a 5x2m enclosure. Max Height: 2m. A generic system diagram is included below. The system must be capable of testing machines in a range of 0.5m diameter and 0.5 m axial length to 1.0 m diameter and 0.75 m axial length. Power Level and RPM Range: Minimum power level: Minimum power of 20 kW Minimum RPM range: 20-100 rpm. Ability to apply in the region of 50 kN of force in at least the X and Y axes applied to the Rotor, with a moment about the vertical & horizontal of 25 kNm Four-quadrant Drive: The system must include a four-quadrant drive machine & four-quadrant drive for the motor/generator under test. The drive for the motor/generator under test should be bypassable to allow custom drive units to be connected. Minimum torque requirement: (@ 100 rpm): 2000 Nm Measurement Equipment: Must include a means of measuring non-torque loads (fx, fy, and fz) for the non-torque loading, and a torque meter on the test machine. Testing Modes: The system must be capable of testing machines in both motoring and generating modes. Platform Mounting: It must be possible to mount the platform to a structural concrete floor that has a top layer of 175 mm total thickness. The top layer consists of 100 mm of rigid extruded polystyrene (XPS) insulation and 75 mm of cement screed. Emergency Stop: The system must include provision for an external emergency stop interlock to be connected. Typical electrical machine under-test: 1m outer diameter and 0.4m in axial length Auxiliary Systems: The system must include all necessary auxiliary systems such that it is ready for operation when powered.

Options: Potential for renewal to incorporate long-term servicing options.

Renewal: Potential for renewal to incorporate long-term servicing options.
