Motors & Drives

Twenty years ago in 1988, John Driver the founder of Dirt Driver Ltd was searching for an electric motor supplier in order to enhance the reliability of the company’s high pressure steam and cold water washers which are used right across industry.

The HNC100-3x® digital servo drive from Rexroth is a programmable, multi-axis NC controller, with field-bus interfaces, specifically developed for control of electrohydraulic drives. It expands the range of tailored automated solutions of Rexroth’s HNC100 family by offering control of up to four electrohydraulic axes in one unit.

The Inverter Drive Supermarket has developed a Dynamic Brake Resistor calculator designed to accelerate the braking specification process in Variable Speed Drive applications. Simply by specifying the required impedance in Ohms and (optionally) the continuous load in Watts, the calculator will search 880 resistor combinations to suggest the most appropriate configuration to suit the application. The results include the total resistance and load, quantity of resistors required, wiring diagrams together with the price and option to buy the configuration for delivery worldwide.

The latest range of torque motors from Parker Hannifin has been designed to help end users of heavy duty industrial machinery replace traditional motor and gearbox mechanisms with a highly efficient direct drive system. Used in conjunction with Parker’s variable speed drives, the new torque motors are intended primarily for use with plastics and rubber extrusion machines, and with injection moulding, mixing, crushing and winding equipment; in each case, the new motors can help to reduce energy and maintenance costs, thereby improving productivity and profitability, and provide greater reliability and overall levels of performance.

Mclennan Servo Supplies has released a new miniature brushless DC motor with integral drive electronics for precision speed control from Netherlands motor manufacturer Allied Motion/Premotec. Measuring just 32 mm diameter with a nominal length of 42 mm, the compact BL30 EB delivers an output torque of 30 mNm at 3500 rpm with an 11 W power output rating. The motor’s outer rotor design ensures minimal cogging and a high-load bearing system and IP54 protection sealing makes it an ideal choice for small pumps, laser scanning heads, fans, medical devices and other applications where compact design, long life and high performance is essential.

Chemineer announces the first static mixer, the first to use Particle Image Velocimetry and Computational Fluid Mixing to ‘visualize flow patterns, and the first manufacturer to produce a gearbox designed specifically for the mixing industry.

The latest servo drives from Parker Hannifin, the world’s largest manufacturer of motion and control technology, form a vital element in groundbreaking all-electric tube bending machines from Unison. Parker’s servo drives are enabling users of these innovative tube bending machines to achieve savings of up to 90% in energy costs in comparison with conventional hydraulic equipment. The all-electric machines are also providing a more accurate, user friendly and cost effective solution, in addition to minimising the environmental impact of tube bending operations.

JVL’s new additions to the fold comprise two complete, high-capacity MAC Servo Motors with ratings of 400W and 750W. These new products were first revealed at the Danish Herning Tech trade fair this year. The MAC motor consists of a complete servo system, including a high-dynamic AC servo motor, hall-sensor, encoder, power supply, driver and positioning controller, as well as facilities for incorporating various modules such as Profibus, CAN, Nano PLC, etc.

Modular, highly integrated and fully functional, Rexroth has announced another milestone for IndraDrive with the launch of the IndraDrive Mi. Through an innovative design build concept, engineers at Rexroth have reduced the total build space required by over fifty percent when compared to traditional servo drives.

Midwest Motion Products is pleased to announce the release of a new DC Gear Motor, the Model No. MMP-PDSF80-12V GS-180-LS. Accepting any 12 Volt DC source, including battery power, this robust Gear Motor measures just 2.8” in Diameter, with a 3.15” Square Gearbox, by 6.2” long, and has a keyed output shaft of 10mm diameter by 27mm long. Easy mounting is accomplished with 4 M5 threaded screws, equally spaced 66.5mm apart.
