New range of ultra-compact brushless AC servo motors
Baldor is introducing a range of ultra-compact brushless AC servo motors offering machine builders a high-performance and low-maintenance alternative to stepper motors and DC servos. Capable of delivering peak torques of up to 3.8Nm, combined with dynamic performance attributes such as fast acceleration, the new motors are packaged in small 40 and 60mm square bodies.
Designated the BSM R-series, the new motors are expected to appeal to automation equipment builders seeking to improve the productivity of machinery in applications such as packaging and labelling, materials handling, semiconductor manufacturing, winding and printing. Special features employed in the motors' construction mean that their action is virtually 'cog free', providing very smooth motion at slow speeds. This also makes the motors suitable for precision motion such as might be required in medical equipment, semiconductor processing equipment and instrumentation and other applications.
Customers can choose from either 40 or 60mm square frame sizes, and one or two winding stacks. This provides a selection of continuous stall torque ratings spanning 0.16-1.27Nm and peak torques from 0.48-3.8Nm. The smallest one-stack motor measures 40mm square by 59mm long and weighs just 0.4kg. Power and feedback connections to the motors are made by long flying leads.
Users can optionally specify motors with a resolver or 2000PPR encoder fitted for positional feedback. A further useful option is the addition of a 24V DC brake.
Baldor offers a comprehensive range of drives and motion controllers to support the new motors, which complement the company's existing broad range of brushless AC servo motors, the BSM N and C series, providing torque ratings from 0.45-40Nm.
