Vertical Hollow Shaft Motor Units and Other RDrive Mounts

January 03,2019

What plays a role when you select an actuator to implement an automation project? Apart from the obvious criteria of price-to-performance ratio, important points include compactness, ease of integration, and usage flexibility. The products in the RDrive servo lineup are designed to drive various machinery as vertical, horizontal, or tiltable hollow shaft motor units. The choice of a mounting alternative is rather a matter of application particulars because the mechanical interface enables installing the engines upright, in parallel, or at an angle. The body design—with a through or a solid bore—is a customizable feature, available upon request. Let us explore the options to see whether and how they can work out to your advantage.

Custom servo motors: why and when?

December 11,2018

More often than once in a blue moon, a newly purchased engine would fail to meet expectations—in terms of performance, sizing, ergonomics, or cost of ownership. Some features turn out superfluous, whereas essential functions are missing. A wise solution to save disappointments and prevent trouble before it actually happens is to go after custom servo motors from the start.

A Small Servo for Higher Performance

December 06,2018

Imagine a huge open space domineered by a giant engine and a formidable main shaft, hardly visible amidst hundreds of smaller subsidiaries—driving belts, gears, and other tackle. That’s how a manufacturing facility looked like in the nineteenth century, when steam machines ruled the world. The invention of an electromotor has changed things remarkably, enabling to operate equipment not from a single “boiler,” but from individual drives, with performance times more efficient. As smaller servos came to the forefront, manufacturers got a chance to minimize workspace utilization, while obtaining more power and precise control over motion.

A small servo motor: when powerful is not equivalent to big

November 15,2018

Miniaturization is a global trend aiming at maximizing user gains, while minimizing space, resource, and energy takeup. Companies strive for more power at lower cost and in a compact size. Small servo motors seem like an an answer to the manufacturers’ prayer. Though unimpressive in terms of dimensions, the devices deliver consistently high torque and boast stable performance over a wide range of velocities.

DC or AC Gearmotor: What Are the Gains?

October 24,2018

As evident from the name, a gearmotor is a DC or AC electromotor merged with a gear train into a single housing. The train is a simple mechanism meant to reduce the rotational speed of an engine, while increasing its torque. On the inside, it comprises a set of gears engaging with each other to create a mechanical advantage expressed as a gearhead (reduction) ratio. The value quantifies to what extent the train can affect the rotational force of a gearmotor. For instance, when applied to a 100 RPM and 10 Nm motor, the ratio of 1:10 enables achieving the output of about 100 Nm, less gearbox efficiency losses.
