Low inertia motors drive motion control
Baldor has launched a new range of brushless servo motors for precision motion control applications, based on rare-earth neodymium iron boron magnets.
Although aluminium is used for the frames, the performance and reliability of the motors is not reduced, through a combination of factors including work-hardened surfaces for the bearings, grade N rotor balancing, and phase-to-phase insulation - which particularly helps to assure long lifetimes when driven by inverters.
Known as the IEC Metric Frame motor range, Baldor will additionally support this product launch with stockholdings at its European warehouse operation, allowing motors to be supplied quickly anywhere in Europe.
This provides efficient and cost-effective support for OEMs, and is also ideal for maintenance companies who need to effect repairs rapidly.
As standard, the motors feature a totally-enclosed, fan-cooled (TEFC) construction, in IEC frame sizes from 60 to 132, in 2-, 4-, 6- or 8-pole speeds, and meeting 'Eff 2' efficiency levels.
Users can choose from B3 foot, B5 D-flange or B14 C-face mounting.
All the motors are rated for IP55 protection as standard against ingress.
For frame sizes up to 100, users can choose versions in delta wiring configurations for operation at 220/240VAC at 50Hz or 250/280VAC at 60Hz, or star-wired configurations for operation at 380/420VAC at 50Hz or 440/48VAC at 60Hz.
For frame sizes of 112 and above, the ratings are 380/420VAC and 440/480VAC in delta, and 690VAC in star.
Users may additionally specify motors with a range of modifications including compliance with UL 1004 and CSA C 22.2 standards, premium 'Eff 1' grade efficiency, class H insulation, IP56 protection, and integrated brakes.
For larger power ratings up to 37kW (frame sizes up to 200), Baldor offers a complementary range of cast iron IEC frame motors. Request a free brochure from Baldor UK ...
