E 1145 - JOAP

Page 4 of 16 Product Description SpeedControl 1145 is a single phased supplied drive for control of PMSM and BLDC and motors up to 3000W/ 3 x 14A. SpeedControl 1145 is enclosed in an IP 20 metal housing for demanding environments. The compact construction, very low sound level as there is no active fan in the drive and the fact that it is maintenance free makes it suitable for many applications. All parts are integrated in the drive which makes no external capacitors or inductors required. Active cooling is not included. The SpeedControl 1145 has integrated APFC (Active Power Factor Correction). The APFC prevents the drive from contributing significantly to the harmonic currents on the grid which is a problem for many drives. Harmonic currents impair the reliability of the mains resulting in poor use of the grid and in house electrical installations. This is partly due to the fact that current and voltage are not in phase, but more so due to non-linear components that are used in all electronic products which generate a wide range of harmonic currents at 150Hz, 250Hz, 350Hz etc. etc., which should not be present in 50Hz installations. These harmonic currents accounts for a considerable loss of efficiency. To protect the grid there are a number of legislative regulations (EN61000-3-2) which must be observed when releasing a drive. Furthermore drives used in other type of products, particularly when these are used in domestic housing, drives are subject to strict requirements to ensure high efficiency (ECO design) and efficient exploitation of the building installations. These requirements can be met in various ways depending on the size of the drive. Therefore we also offer several solutions including an APFC which by using an advanced power entry enhances our largest frequency converter, offering a very high performance and a cost-efficient use of the electrical installation. To reduce the overall cost and minimize installation work, an APFC has been integrated in SpeedControl 1145. This makes SpeedControl 1145 an all-in-one solution which also includes an EMC filter to ensure that we also meet the requirements of the EMC Directive. Many manufacturers choose to use an A2L or A3L refrigerant to reduce the use of refrigerant with a high GWP (Global Warming Potential). The SpeedControl 1145 is designed to be in compliance with the IEC 60335-2-40:2016 with respect to the A2L refrigerants. It is also possible to use the SpeedControl 1145 for applications using A3L refrigerant all though it will require a close cooperation between LS Control and the manufacturer. The SpeedControl 1145 range is a new series of unique PM motor drives designed for the growing market of energy saving units. It is also a sensor less drive – which makes mounting of sensors in the PM motor obsolete. The drive is available as standard with cold plate or heat sink for vertical or horizontal mounting. Permanent magnet synchronous motors (PMSM) are highly efficient and widely used today for fans, compressors, pumps and other applications. Compared to conventional drives and AC motors, the new EC and attached PM motors are considerably energy saving, improving the efficiency of the finished unit significantly. PM motors have the flat characteristic that the torque is almost constant during the controllable speed range. These motors typically have an efficiency above 94% by using a correct drive. However, the rapid development within the technology and the motor is controlled by using of motors results in new and improved motors continuously. The SpeedControl 1145 employs the latest technology within sensor less FOC Sinusoidal motor currents control of PM motors. Motors must be matched to the drive for optimum performance and energy savings. A number of profiles are already available, but if the motor profile for a specific compressor is not available, there is a new tuning procedure making tuning to new compressor models and motor profiles available at any site, i.e. customer site, manufacturer site etc
