Adding to the range of Fenner Power Transmission products are the new Fenner inverters and electric motors offering simple, precise and powerful control, delivering the very best in performance and energy efficiency - time after time. From initial electrical input through to the final driven machine, Fenner can now offer a complete solution.

The new QuickDrive (QD) range of inverters available from ERIKS UK. Available in a number of designs, including IP55 variants of the QD:E and QD:CT PLUS that are suited to harsh environments, the QD range is incredibly easy to install and commission yet rich in features and functionality. The range caters for variable torque applications and those needing high performance open-loop requirements and simple speed control such as Heating, Ventilating and Air Conditioning (HVAC).

The Fenner QD:E (Easy) range is a basic, simple-to-use drive available in ratings from 0.37kW to 11kW. The range is competitively priced, with factory pre-set settings that are suitable for most applications. For more complex applications, the 14 basic parameters can easily be adjusted to suit more demanding requirements.

The QD:E units have an overload capacity of 150% for 60 seconds, and are supplied with an integral RFI filter. Repeat programming can easily be carried out with the aid of the new Fenner Q-stick, a memory stick that simply plugs into the front of the drive to allow the specific parameter settings to be uploaded extremely quickly and efficiently.

Suited to providing energy savings in HVAC applications is the QD-VT (Variable Torque) range. This range is specifically designed for use with fans and pumps and is available with ratings from 1.5kW up to 160kW. Integral RFI filters are fitted as standard and each drive is capable of a number of real-time energy optimising functions, together with integrated PID (Proportional Integral Derivative controller) functionality.

The advanced QD:CT (Constant Torque) Plus range offers open-loop vector control for motors with ratings from 0.37 kW to 160 kW. These drives are capable of delivering 200% torque right down to 0 Hz, allowing them to be used in many applications where closed-loop control would have previously been essential.

Setting up QD:CT PLUS drives is simplicity itself, to achieve optimum performance, all that is needed is the data found on the motor plate. The drive will then continuously (and automatically) track the motor characteristics and using the vector control algorithms adjust for optimal performance ensuring maximum torque at low speeds.

Completing the range are the enclosed QD:E IP55 and QD:CT PLUS IP55 units that offer a fully weatherproof drive suited for even the harshest of industrial environments. The front facia comes complete with speed control knob, forward/reverse selector, lockable isolator and full programming keypad and display. Fenner QD drives from ERIKS are MODBUS compatible and can be converted to allow easy integration with Fieldbus and Ethernet connections via the RS485 port. All QD drives can operate in ambient temperatures from 0°C to 50°C for IP20 units and 0°C to 40°C for IP55 units. The QD range is fully compliant with both the ROHS and EMC directives and is UL/CUL approved.

The FM:P premium efficiency electric motors, completes the new range of products. The Fenner FM:P is an ECA compliant, high efficiency motor that has been designed to work in the most demanding applications. Available in powers from 1.1 to 500kW, these motors feature NU bearings on larger motors to prolong bearing life where there is a considerable overhung load. Optimum energy efficiency is guaranteed by the use of high quality materials and qualifies the range for EFF1 status.
