Parallel Shaft Gearmotors Have Improved Power and Performance

Feb. 28, 2013
The redesigned 42A5-FX permanent magnet (PMDC) parallel shaft gearmotor provides up to 40% more torque than previous E/F models.

Forty new stock models are offered with either 12/24 VDC or 90/130 VDC rated motor windings. New synthetic lubricant allows the gearhead to operate at a wider temperature range while at the same time improving overall gearhead performance. Stronger, hardened helical steel gears and new needle bearings provide more torque and 25% longer product life. The gearmotor achieves these gains in power, performance and flexibility without any change in dimensions or mounting configurations. The gearhead is driven by the company’s 42A5-frame (4.25 inch/108 mm diameter) PMDC motor. Redesigned windings now bring power and dependability to low-voltage solar/battery power applications, as well as those applications using standard 90/130 VDC power (up to 3/8 hp/280 watts). The motor’s high starting torque and linear speed/torque characteristics make it suitable for variable-speed, high-torque applications. The new gearhead provides up to 350 lb-in. (40 Nm) continuous torque. Models are available in gear ratios ranging from 5:1 to 300:1 and rated output speeds of 3 to 500 rpm. Suggested applications include medical equipment, packaging machines, conveyor systems, printing equipment, and factory automation applications.
