HIGH EFFICIENCY PERMANENT MAGNET MOTORS
Saving energy across a wide speed range, the HPS, HPI and HPF permanent magnet motors from Lafert satisfy both current European mandatory efficiency requirements (IE2 and IE3) and the future IE4 standard. As well as saving energy and cutting running costs now, the motors are also said to avoid expensive future motor- related machine re-designs. The HPS and HPI are rare
earth motors while the HPF employs ferrite permanent magnets. All three provide motor size and weight reductions of up to 50% over standard similarly rated units, and offer
between three and four times the power output of existing similar frame size motors, the company explains. The HPF offers the additional benefits of stable pricing and assured supply by avoiding the vagaries of rare earth permanent magnet material availability. The Lafert HPS (High
Performance) motors are compatible with drives that have PM algorithms whilst HPI motors have an integrated drive. The HPF is available with the same drive options. Power ratings are 0.37 – 30kW, IEC frame sizes: 71, 90, 112, 132, speeds up to 6000rpm, and a voltage range of 230-480V. These are suitable for continuous
operation applications, such as pumps, fans and compressors, or where low residual heat is required.

GENERAL-PURPOSE INVERTERS
Modular in design, the C2000 series general-purpose inverter from Delta Group has multiple options for extended I/O modules, encoder feedback and communication accessories, hot pluggable keypad replacement, removable fans and power indicators. With both closed-loop PID and sensorless modes, this enables permanent magnet (PM) and asynchronous (IM) motor control, and assures precise speed, torque and positioning across a broad range of operating conditions. Features include a power
range of 0.75-90kW at 230V, or 0.75-450kW at 460V; and it offers safety features including a built-in braking unit (up to 30kW on 460V models) and certified ‘safe stop’
functionality (STO SIL2). It also has a MODBUS
communication interface, while the CANopen (DS402) master
function can control up to eight slave drives simultaneously. There are also several optional cards available for PROFIBUS- DP, DeviceNet, MODBUS TCP and EtherNet/IP communications. Of additional benefit, the series is environmentally adaptable,
with low EMC emission levels, an onboard EMI filter to reduce electrical noise, and a DC choke to suppress harmonics. The C2000 Series uses a Class 3C2 conformal coating and can be installed in flange-mount or wall-mount to provide optimal heat dissipation. It is also capable of self-diagnosis. While in FOC+PG mode, this AC motor drive features output up to 150% of starting torque at zero speeds. Rated to ambient temperatures between -10˚C to 50˚C, the C2000 series has a rugged IP54 cabinet designed to prevent contamination by dust, dirt and liquids in harsh environments. It is suitable for a wide variety of power control applications,
including construction and overhead cranes, printing and packaging equipment, textile machinery, compressors and more.

VSDS FOR MACHINE MANUFACTURERS
Designed for machine manufacturers, the Altivar Machine range of variable speed drives (VSDs) from Schneider Electric offer a range of benefits, with two complementary models – the Altivar 320 and Altivar 340 – leading the lineup. According to the company, the VSDs
match a variety of machine throughout requirements thanks to their: open-loop motor control with torque sensitive operation, even at low speed and dynamic accuracy for start/stop applications; closedloop motor control for applications requiring velocity sensitive operation or precise positioning; and advanced connectivity. The drives are designed to provide
continuous machine operation in harsh environments with high levels of ambient temperature, dust, electrical interruptions, or mechanical disturbances. They also maximize machine operating time and reduce total machine cost thanks to reduced installation costs, fewer additional devices, and reduced engineering and design time, the company adds.

SERVO MOTOR RANGE ENHANCED
New feedback device options and connector options have enhanced the Kollmorgen AKMH range of stainless steel servo motors, which are available in the UK from INMOCO. These CIP compatible motors now
offer greater integration opportunities, enabling demanding hygienic applications to benefit from the same performance options as standard automation applications. New resolver, comcoder (2048ppr), hyperface (SKx36 and SRx50) and EnDat 2.1 (optical and inductive) feedback options are provided, and new flying lead and connectorised versions are available, along with IP69K and IP67 vented cable-mounted connectors, and IP69K cable and tubing versions. The updated motors also offer
two-cable versions and they now have an integrated brake. The motors conform to the Machine Directive 2006/42/EC 3A hygiene standards, while lubricant and seals adhere to FDA standards.
