BLDC series brushless DC servo motors and matched BD series drives for low-cost speed control applications are now available in the UK and France from motion control specialists Mclennan. The new drives are particularly aimed at cost-sensitive OEM applications for driving packaging conveyors, transfer & elevating stations, material feeders, mixers & agitators, pumps, valves and closures – where straightforward speed control operation, long working life and competitive price are important considerations.
The high-performance 42mm brushless DC motors are optimised for velocity loop feedback, and are available in three frame lengths for a continuous rating of 105W, with a peak torque of 0.45Nm and speeds to 4500rpm. The matching panel mounted BD5 series drives offer a 5A continuous and 10A peak current rating from a 12 to 48V DC power supply. A flexible choice of speed setting features include on-board trim pot, 0–5V analogue input or seven pre-set speeds selected from the drive’s digital inputs. Acceleration and deceleration may also be set from an on-board trim pot. Soon to be introduced, the BD series drives will also include a 10A continuous version to match a larger 57mm diameter motor that will offer even more power and torque performance.
Additional drive I/O includes direction, stop, and enable inputs with fault output and a motion tachometer output that may be used to synchronise other processes. I/O may be factory reconfigured to suit specific applications for OEMs along with modified shaft and mounting mechanics on the motors. Accessories include mains power supplies, regenerative clamps and motor-to-drive cable assemblies in a choice of 1m or 3m lengths that will make installation straightforward.
