During the last few years, there has been a growing interest in direct drives. Small wonder as they offer various advantages when designing competitive machines and systems, provided that the necessary electrotechnical and mechanical knowledge is available. GFC direct drives generate a high torque (torque motor) or a high thrust (linear motor) at low frequency. They run at low noise, evenly and operate efficiently and with high precision during their entire lifetime. Furthermore, direct drives are economically viable. Cost-intensive maintenance becomes obsolete as there is virtually no mechanical wear. Should repair become necessary, the motor is replaced as a whole. A lubricant is not required – another environmentally friendly aspect. |
