AC / DC Motor Drive Controllers

Regardless to the type of motor used, an electronic device that can continuously modify the power supplied to a motor is typically referred to as a ‘Drive’.  A Soft-Start is a lower cost alternative to a Drive that offers only ramped acceleration to motor rated speed and some units may also have a deceleration ramp. As a minimum a drive allows speed control of a connected motor whilst more advanced units offer torque and position control and monitoring. Many traditionally fixed speed applications can benefit in speed control of a motor to reduce the power consumption and wear of mechanical systems. Torque control can be used in applications such as tension regulation in roll winding and web handling applications. Torque limitation can be programmed to avoid overloading of connected loads, similar to a mechanical clutch. Quince Automation has designed and commission many types of motor / drive systems including :-   AC Inverter with encoder & sensor-less Vector   AC & DC Servo   DC thyristor   Stepper in open and closed loop   Common bus systems   Using drives from brands such as :- Siemens – Micro Master, Midi Master, Master Drive, Sinamics Control Techniques – Mentor, Unidrive, Commander SK Lenze – various Allen Bradley – PowerFlex And many others …. Connecting a PLC to a Motor Drive via a communication link such as Profibus or ProfiNet can unleash a host of other benefits for monitoring and diagnostic functions, two obvious parameters to monitor would be power consumption and temperature; just these alone can give early indication of pending mechanical failure.   We can design a complete system of PLC, HIM/Scada and Drive System for your application or upgrade an obsolete Drive installation. .
