WHITE PAPER STARTING EARLY: WHY YOU SHOULD CONSULT YOUR MOTION SYSTEM ENGINEERS AT THE ONSET OF NEW OEM PROJECTS Electric motors — along with their power transmission, feedback and control devices — are critical to machines that rely on motion axes. Original equipment manufacturers (OEM) embarking on a new product’s development should therefore involve the motion specialists as early as possible in the project’s design. Since the motor and its output have a broad impact on the equipment’s overall design, early inclusion of the motion system experts will optimize the performance of the equipment and also streamline project development. This is especially the case for precision equipment that requires a miniature motor and motion system. MINIATURE MOTORS ENABLE MORE PRECISE CONTROL By controlling the torque, speed, acceleration and shaft position, the electric motor is the fundamental component that brings to life a variety of systems — from surgical robots to industrial machines. Some of these applications don’t require more than 1 kilowatt (kW) of power, necessitating small, lightweight motion systems. Compact motion systems — which typically generate less than 1 kW and measure roughly 90 millimeters (mm) or less in diameter — must often meet complex application requirements. The motors and control systems that guide satellites or power the joints of a surgical robot, for example, need to provide pinpoint precision. Similarly, the motors that control medical equipment, such as patient infusion systems, must ensure absolute reliability. Such reliability is also a typical requirement for mission-critical military applications.

These aspects will impact the equipment’s ability to fulfill its tasks according to the application’s speed and accuracy requirements. They will also affect the equipment’s ultimate size and weight, as well as its time to market and development costs, making it highly beneficial for OEMs to include the motion system experts at the earliest possible stage of a new project.

INCLUDE THE MOTION SYSTEM EXPERTS AT THE IDEATION PHASE When OEM engineers turn their attention to concept development — and preferably, when they’re still in a product’s ideation phase — they should consider the motion system. Even if the discussions only include general assumptions of the motion system’s design, consulting the motion system engineers at this point will ensure later design choices aren’t constrained. Every OEM project has design objectives that are, more or less, set in stone. These attributes often relate to precision, speed and reliability — all of which significantly depend...

CONFIRM THE MOTION SYSTEM’S DESIGN PRIOR TO THE FEASIBILITY PHASE The feasibility stage is often the longest period in a project’s design. However, at this point the motion system’s form factor and performance requirements shouldn’t change in any significant way so long as the OEM has already made the appropriate decisions during earlier phases. Instead, motion system engineers should use the feasibility stage to fine-tune their motion solution to optimize the system’s performance and efficiency. If the motion system design hasn’t been confirmed at an earlier stage, the decisions taken now —...
