Lenze has extended its range of SW aluminium worm geared motors by introducing a new helical worm series that allows low output speeds of 3-18rev/min.
Lenze has extended its range of SW aluminium worm geared motors by introducing a new helical worm series that allows low output speeds of 3-18rev/min.
The new gearboxes feature an additional stage, which enables operators to minimise costs and maximise profit.
The new PC-SW range, which can be built to order from stock parts, incorporates a helical stage fitted between the motor and the worm gearbox.
This additional module can increase the gear ratio by a factor of three thereby providing low output speeds while maintaining high efficiency levels which, depending on the ratio, can range from 45 to 70%.
Output speeds from four and six-pole motors extend from 3 to 19rev/min, and rated torques can reach 516Nm.
The lower output speeds are produced from standard modules that retain the same output dimensions to those found on Lenze's existing worm geared models.
This minimises manufacturing costs and means the new PC-SW helical motors offer exceptional value for money.
Flexibility is also secured through the modular design of the PC-SW range, which includes standard hollow shaft output and a full range of mounting options, including single/double shafts, torque arms, feet and flanges.
There is also a choice of motors, including one and three-phase drives and braked, flameproof and DC variations.
While commenting on the versatility of the new PC-SW range, Geoff Spear, Marketing Manager at Lenze, also alluded to the motors' competitive price.
"The new helical worm models are adaptable to motor powers ranging from 90W to 750W and they are able to achieve this level of performance by utilising a standard modular design.
This means we can use stock parts to manufacture the PC-SW range and therefore keep costs down.
The result is a keenly priced, highly versatile range of geared motors".
