Geared AC motors offer long life
Geared motors, which cover powers from 6 to 90W, are now established in the worldwide market and have established a reputation for quality, value and long life.
Lenze are official distributors for Panasonic, one of the largest motor manufacturers in the world Panasonic developed the G-series range of geared motors which cover powers from 6 to 90W

Low cost servo systems replace variable drives
The availability of intelligent, low cost servo systems means that servo technology is being employed on machines which were once the preserve of mechanical or inverter variable speed drives.
These units are now established in the worldwide market with a reputation for quality, value and long life.
The PPMA show held in September 2005 at the Birmingham NEC proved the popularity of the range with many of the displayed machines using the G-series range.
The G-series range of geared motors are designed for single and three phase supply, the single phase are suitable for fixed speed running in a power range of 6 to 90W.

Alternative drives prevent conveyor seizure
Alternative drives have cut the cost of replacement by half for a seized packaging conveyor control system at cod liver oil capsule manufacturing plant.
The three phase ranging from 25-90W have two versions, 230V ideal for variable speed control with an inverter and the 400V version designed for fixed speed running.
All 6 to 40W models are all self cooled while the 60 to 90W units are supplied with a cooling fan.
The G-series geared motors are available as standard induction, quick reversible or braked motors.
Standard induction motors are highly efficient and quite in operation.
The same high quality design and basic construction is used throughout the range.
All motors are four pole with a nominal speed of 1500 rev/min at 50Hz.
Quick reversible motors have a plate attached to the end of the rotor which is constantly under friction via four cylindrical brake pads and springs.
The resulting braking torque is continuously applied to the motor even during motor running.
When power is removed, this friction results in faster stopping of the motor.
The brakes in the braked motor models release when power is turned on leaving no residual torque, so when the motor is switched off the brake engages.
The gearboxes are available in standard ratios of 3:1 to 200:1 and use a combination of helical and spur gears for high speed efficient running.
Where high rations and lower speeds are required, an intermediate decimal gearbox is available.
If variable speed is required the 230V three phase geared motors can be used with the Panasonic Micro-Inverter.
This combination offers excellent speed/torque characteristics and good dynamic motor performance.
Other inverters with higher functionality can be used, for example the Lenze smd with its unique memory chip which contains the entire drive and motor configuration and can be easily removed and replaced for fast and efficient program changes, saving time and money.
With the G-series suitable for conveyor, food machinery, packaging, pumps, labelling and test equipment applications, it is no wonder that many of the packaging industries top manufacturers include the G-series in show machinery. Request a free brochure from Lenze ...
