What machine safety functions address speed, and when are they used?
The Machinery Directive 2006/42/EC states that when a machine manufacturer is unable to eliminate the risks of potential hazardous situations (for example, mechanical hazards such as crushing or cutting) through safe design methods, the next step is to reduce the risks through technical protective measures. These technical measures include protective devices, such as door locks […]
Stepper motors feature on-board drive and control
Delta Line has expanded its offering of motors with integrated electronics to include stepper motors. These smart stepper motors eliminate the need for a separate drive and controller, providing a complete stepper motor solution in a single, easy-to-integrate device. Delta Line’s ISI57 and ISI60 stepper motors with integrated electronics provide significant space savings, not only […]
Ultra-small pancake-style gimbal motors from Orbex
Orbex Group debuted a line of ultra-compact high-performance gimbal motors. Featuring a pancake-style form factor, the motors are wound to operate at low speeds typical for gimbals while exhibiting a high torque constant for fast response when needed. The new gimbal motors are engineered to minimize cogging torque, ensuring smooth rotation for stable imaging or […]
When is motor output power a useful specification and how is it calculated?
In motion applications, motors are typically chosen based on their torque and speed capabilities, using a torque-speed curve that describes the motor’s performance when paired with a specific type of drive and operated under specific conditions. But motors can also be rated, or specified, by their output power. Here, we’ll look at how output power […]
Haydon Kerk Pittman launches new online motor calculation tool
Haydon Kerk Pittman, a business unit of AMETEK’s Advanced Motion Solutions division, has released its new Pittman Express online motor calculator. The Express tool lets users identify and select the right motor for their applications quickly and easily. When a user enters an ideal load point, torque, and speed, the Express tool returns a list […]
STXI Motion expands integrated closed-loop servo-stepper motor line
The stepIM NEMA 17 EtherCAT model from STXI Motion is the newest addition to the company’s family of integrated closed-loop servo stepper motors. The IP65-rated stepIM NEMA 17 delivers an efficient and economical solution for applications requiring the performance of a servo at the price of a stepper. “The new stepIM NEMA 17 closed-loop stepper […]
Motion system design: How to manage inertia mismatch
One of the most important parameters when sizing a motion system is the inertia of the load being moved. Regardless of the type of motor being used — AC induction, stepper, brushless DC, or AC servo — the ratio of the load inertia to the motor inertia has an important influence on system performance. If the […]
New asynchronous motors from NORD feature optimized design for improved performance
NORD’s newly redesigned 100 frame motors are the first step in updating their asynchronous motor portfolio with an optimized electrical, mechanical, and visual design. The new 3 and 4 hp premium efficient motors offer a simplified assembly including the elimination of a copper rotor as the motors produce the same energy efficiency without it. This […]
Why do stepper motors vibrate and what are ways to avoid or dampen vibrations?
With each discrete step that a stepper motor makes, the inertia of the system causes the motor to slightly overshoot (or undershoot) the intended step angle. The motor then oscillates, or “rings,” until it finally settles at the commanded position. If the frequency of these step-by-step oscillations is at or near the motor’s natural frequency, […]
