A range of brushless servo motors, just released from Baldor, is based on rare-earth neodymium iron boron magnets. The magnetic material used provides near-identical low-inertia responsiveness of motors employing samarium-cobalt magnets, but at a typical cost reduction of up to 8%.
This feature delivers a useful saving for OEMs building equipment requiring high acceleration and speeds, such as machinery for packaging, labelling, pick-and-place and positioning. The motors additionally form part of Baldor’s stock profile for Europe, supporting OEMs, end users and companies building equipment to demand in small quantities.
Suiting precision motion control applications, the BSM-N Series offers users a wide choice of frame sizes with peak torques as high as 40Nm and a choice of maximum speeds. A rugged brushless resolver is integrated into the motor for simple system building and incremental encoders are also available.
The motors are available in three lengths with single, dual or triple stacks of magnets, allowing users to match performance characteristics easily against particular application requirements.
Standard build options include an enclosure and shaft oil seal to meet IP65, and the provision of an internal holding brake. All units are CE marked and also comply with UL and CSA standards.
