The combination of the BK17 range and permanent magnet synchronous motors (PMSM) means not only that the PMSM design is superior at converting electrical energy into mechanical power, it also offers the added benefit of maintaining constant speed independent of the load. This means that motor speed does not vary - despite overload variations or cases of voltage drop - as long as the mains frequency is kept constant. PMS motors are perfectly suitable as drives for applications with constant torque such as conveyor systems.
HiflexDRIVE in Aseptic Design
Aseptic drives are carefully designed for applications where regular washdowns are required to maintain a clean environment. The motor is designed so that a fan and cooling ribs are not required, thereby allowing for a completely smooth outer casing with a non-drive end which is sealed. This eliminates any dirt traps on the motor casing and also prevents re-infection of the local environment caused by air movement from a cooling fan.
The design also includes a very high level of ingress protection, up to IP69K; which is a special designation for washdown applications involving high pressure, high temperature water. In addition, the aseptic drive is painted using an acid and alkali resistant formula, which can withstand chemicals with a pH range of 2 – 12. As a result the new drive system can withstand the cleansing solutions and disinfectants that are commonly used without affecting its performance.
