Small geared motors hit the spot
Accurate speed holding without panel space
Panasonic B-series brushless geared motors available through Techdrives deliver two big benefits:- spot-on accurate speed holding over a 100:1 speed range and an integrated drive that means no panel space is required. B-series geared motors are available from 30 to 130W with different gearheads for a range of rated speeds. They particularly suit small machines that need a precision drive, for example checkweighers and metrology equipment.
The Panasonic B-series brushless motors are fitted with hall-effect sensors that give feedback to the drive which is fitted to the back of the motor. The assembly is compact with a body length of only 215 mm for a 130W geared motor, and the IP65 enclosure suits all types of machinery including food production. Electrical supply is single phase and the drives are rated for ambient temperatures from -10 to +40ºC. Eight different gearheads fit to the motor giving rated output speeds from 30 to 1000 r/min. The speed holding accuracy is excellent with a variation within +/- 1.0%.
The standard brushless geared motor is the B1 and there is also a positioner variant, the B3. This gives simple 4 point positioning with a step angle at the motor of 1.25º in the same dimensions and IP65 enclosure as the B1.
Most models in the Panasonic B series range can be built from stock and full details are given on the Techdrives website www.techdrives.co.uk. Optional cables and keypads are available and the programming software is free of charge. With compact dimensions, a maintenance free design and no requirement for panel space, the Panasonic B-series is the ideal drive for small precision machines.
