A motor winding configuration determines how well an electric motor matches an application's voltage, current and speed requirements. In this article, we explain Alva’s winding codes, such as 2D, 4Y and 8Y, and how series turns and Star/Delta connections affect torque constant, voltage constant and speed range. Learn how winding configuration influences servo drive selection and how to select the right configuration for your application.

Learn how integrating frameless slotless motors with different gear topologies enables more compact, torque-dense actuators. This guide explores planetary, strain wave, cycloidal, and ball screw systems, along with the key engineering considerations for designing high-performance motion systems.

Trondheim, Norway – August 13, 2026 – Alva Industries (Alva), a manufacturer of frameless motors and owner and creator of FiberPrinting™ technology, has appointed Andrea Annunziata as Director of Product Management and Applications Engineering, strengthening the company’s product and applications leadership as Alva continues to develop its portfolio of high-performance electric motors.

How do you mount a frameless motor rotor? In this Tech Torqs episode, we explore common mounting methods - including press fits, shrink fits, and adhesive bonding - and explain how proper assembly helps ensure long-term motor performance.

Selecting a frameless motor is about more than comparing torque values. This article explains how to correctly interpret motor datasheets by understanding continuous and peak torque, torque saturation, motor constants, winding configurations and drive limitations - helping you avoid common selection mistakes and choose the right motor for your application.
