Alva launches TorqStudio software platform for electric motor design, analysis

Norwegian frameless motor provider Alva Industries announced the launch of TorqStudio, a new software platform that the company said enables engineers to design, optimize and analyze electric motors before committing to prototypes or hardware.

Alva said that TorqStudio supports early-stage motor development by allowing users to move from high-level size requirements to fully manufacturable motor designs in minutes, and to validate performance at defined operating points using in-house developed analytical models.

Motor design from simple size constraints

TorqStudio users begin by defining basic motor constraints such as outer diameter and axial length. Based on these inputs, the platform automatically generates thousands of candidate motor designs and filters them to present only the most efficient offerings.

“With TorqStudio, engineers can move from high-level requirements to data-driven motor designs extremely quickly,” said Anton Franzén, director of product management at Alva Industries. “The platform removes much of the uncertainty typically associated with early motor design and gives users immediate insight into what is technically possible.”

Alva said that each design is evaluated based on key performance metrics, including motor constant and motor mass, allowing engineers to clearly visualize trade-offs and select optimal designs for their application. All presented designs represent complete motor concepts that can be manufactured.

The company said that the selected designs can be saved to a personal design database, exported as datasheets and used directly in further analysis. Users can also submit a request for quotation if they wish to proceed toward development or procurement.

Performance analysis at defined operating points

Beyond design generation, Alva said that TorqStudio provides detailed motor analysis capabilities. Users can define operating conditions such as supply voltage, ambient temperature, cooling conditions, torque, speed and switching frequency, then evaluate how a motor performs at specific operating points.

Results are visualized on speed-torque maps and supported by detailed output data, including:

• Mechanical and electrical power
• DC and AC current
• Efficiency and losses
• Stator and motor temperatures
• Current waveforms

TorquStudio allows for multiple operating points to be analyzed simultaneously, with data imported from tools such as Excel. All results can be downloaded for documentation or further evaluation. Alva added that TorqStudio supports analysis of both custom motor designs created by the user and Alva’s standard motor portfolio, enabling direct comparison within a single environment.

Alva Studios showcased its motor technologies at Automatica and SPS 2025.
