The GP geared motors suit 4-point positioning in a power range 50 to 130W. The KV motors and drives give performance approaching servo levels but at low cost in a power range 50 to 750W. All three MINAS ranges are particularly compact with motor lengths reduced by half and weights by 30%. They give highly accurate speed holding over a wide range. They are also energy efficient with typically 20 percent less losses than conventional motors.
GV general purpose models suit transport drives in check-weighers, inspection ma-chinery and other areas where precise speed holding is needed over a wide range. Three sizes of motor at 50, 90 and 130W are combined with gearheads that have available ratios from 3 to 2000.
MINAS brushless technology results in small sizes, for example the largest 130W geared motor with an output torque of 29Nm has a body length of only 125mm. Torque is delivered with a flat characteristic so there are no starting shocks. The drives are compact too – only 35mm wide. They have RS485 comms, 1 analog input, 8 digital set speeds and optional analogue or digital keypads.
The new GP range looks much like the GV and shares many of the features. Addi-tional is the ability to give 4-point positioning with smooth S-ramps. This suits cases such as indexing, reciprocating drives and door drives. Maximum rated torque is 18Nm and rated output speeds are 60 to 600 r/min.
The third MINAS model is the KV. The motor looks much like a servo motor but the use of MINAS brushless technology results in lower costs. Nevertheless the low iner-tia gives a highly dynamic drive with performance close to true servo levels.
The KV suits speed control and is particularly useful as an upgrade where stepper motor driv-en machines need higher performance. There are five sizes from 50 to 750W and the speed control range is 100 to 4000 r/min.
These new Panasonic brushless drives have high performance in terms of speed holding and speed range. The new MINAS technology gives compact dimensions, energy efficiency and low cost too.
