Product roundup: Motors and drives step up to serve.September 21, 2020
High-voltage drive, high-torque motor
SureStep high-voltage AC stepper drive and compatible MTRAC high-torque motors have joined stepping system motion control products. The drive is powered from 90 to 240VAC, and is intended for use with step motors that handle a high bus voltage of 340 VDC. MTRAC motors work with high bus voltages, providing higher torque at higher speeds.
Stepper drive auto-setup measures motor parameters and configures motor current control and anti-resonance gain settings. SureStep uses AC input 90 to 240 VAC, and output current is selectable from 0.6-2.5A/phase (peak of sine). Microstep resolution is switch-selectable with 16 settings from 200 to 25,600 steps/rev. MTRAC motors are available in single-shaft and dual-shaft configurations with steel rotor case and stainless-steel shaft(s). Motors are available in NEMA frame sizes 23 and 34 with torque available from 75 to 1841 oz-in.
Drive analyzers simplify troubleshooting
MDA-510 and MDA-550 motor drive analyzers simplify troubleshooting on single- and three-phase motor/drive systems with guided testing to quickly captures measurements. MDA-500s eliminates setting up complex measurements, and delivers reliable, repeatable test results.
Users select a test, and step-by-step guided instructions show where to make voltage and current connections, while the preset measurement profile ensures all necessary data is captured for each motor-drive section, from the input to the output, DC bus and the motor.
They measure motor-drive parameters including voltage, current, DC bus voltage level and AC ripple, voltage and current unbalance and harmonics (MDA-550 only), voltage modulation, and motor shaft voltage discharges (MDA-550 only); perform extended harmonics measurements to identify effects of low- and high-order harmonics on electrical power systems; conduct guided measurements with graphical step-by-step voltage and current connection diagrams; use simplified measurement setup with preset measurement profiles to automatically trigger data collection based on the chosen test procedure; and measure additional electrical parameters with full 500 MHz oscilloscope, meter, and recording capability for complete range of electrical and electronic measurement on industrial systems.
MDA-500s also create as-found and as-left reports quickly and easily. Simply press “save to report” at any test point or measurement, and the analyzer saves it to create comprehensive reports that document the troubleshooting process.
Intelligence for fixed speed
VLT Soft Starter MCD 600 combines controls and protections with increased intelligence for performance in fixed-speed applications. It's more flexible to install due to Ethernet and serial-based communication option cards and application-dedicated smart cards. Ease of use is increased with pump-clean function, PowerThrough operation, and calendar or run time-based scheduling. MCD 600 has main voltage ranges of 3 x 200-525 VAC (T5) and 3 x 380-690 VAC (T7), as well as current ranges of 20-129 A (nominal) in an IP 20 enclosure and 144-579 A (nominal) in an IP00 enclosure. It also enables easy application analysis with up to 348 events logged, as well as QR code scan for serial number and event data.
Low-voltage DC drive with snap-on board option
DCL series low voltage, brushless motor control operates in the 12-48 VDC power bandwidth, up to 30 amps peak for 1 minute, or 15 amps continuously. Its design removes many of the trim pots and jumpers associated with typical motor controls, and it can be customized for individual applications.
For users who wish to modify calibration in the field, DCL has a programmer board CPC300-1 (sold separately) that snaps on and provides calibration of 10 different parameters, as well as DIP switches for setting different operating modes. A single CPC300-1, acting as the adder board, can be removed after programming and used with multiple DCL units. Base DCL units are Modbus capable, and come with one trim pot for calibrating maximum speed and two DIP switches for closed/open loop operation, as well as inverting hall effect feedback.

Compact, motor-mounted drives
ACOPOSmotor series has added two compact, motor-mounted drives to save cabinet space, reduce installation costs, and ease development of modular machinery and plants. They cover a power range up to 0.35 kW, while the smallest version measures just 60 x 90 mm. The two drives also have an integrated servo drive that enables control loops as fast as 50 µs, and they're also available with an optional, integrated gearbox and brake. These ACOPOSmotor variants have a 24-60 VDC voltage range, so no special training is needed to exchange devices, while regenerative braking energy can be fed back into the DC bus, reducing energy consumption by as much as 30%. They also have two connections for hybrid cables, so only one cable is needed to connect to the control cabinet. This hybrid cable provides power and Powerlink communications, allows other units to be easily daisy-chained in, and provides STO safety functions that are standard on the motor-mounted drives.

High speed, small package
35ECS Ultra EC brushless DC, slotless, two-pole motor provides high speed, up to 330W continuous power, smooth operation and long life. Its high-speed rotor design sustains a maximum speed of 40,000 rpm, and is available in two lengths, 35ECS60 at 35 x 60 mm with 120 mNm torque, and 35ECS80 at 35 x 80 mm and 193 nMm torque. 35ECS also features a laser-welded front flange to provide the strongest housing for sustaining high-torque reaction. A temperature probe on the coil head ensures an optimized control of motor performances in heavy duty applications. They're also offered with hall sensors and a six different coils to match speed and voltage requirements.
Food-safe, IE3 efficiency, flexible mounting
IEC Food Safe motors are available in the 0.18-7.5 kilowatt power range, and in 2-6 pole versions for 230-690 volts at 50 or 60 hertz. They feature IE3 premium efficiency to reduce energy consumption and emissions. Flexible mounting arrangements ensure they'll fit in almost any application. They come in frame sizes 71-132, and feature smooth, stainless-steel enclosures that are easy to clean and sanitize to meet increasingly stringent hygiene standards. IEC Food Safe motors have achieved IP69 water protection rating, and their encapsulated windings lets them last longer than general-purpose products in tough washdown conditions. Their external surfaces are self-draining with no crevices where particles can collect, and their markings are laser-etched onto the frame, avoiding channels and ridges where contaminants could accumulate. They can also withstand high-pressure sprays and are fully compatible with clean-in-place (CIP) methods.
