HD1 – AC Variable Speed Inverter Drives


The HD1 range of AC Inverters are high performance, open loop vector control drives specifically designed for controlling asynchronous AC induction motors and permanent magnet synchronous motors. Utilising the most advanced sensorless vector control technology, the HD1 range offers unparalleled reliability, environmental adaptability, high precision and stable performance.

What is an AC Variable Speed Inverter Drive?

Whether you call it an AC Variable Speed Inverter Drive, a Variable Frequency Drive, a Variable Speed Drive, Micro Drive, or just an AC Inverter, it is a type of adjustable speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage. AC Variable Speed Inverter Drives are used in applications ranging from small appliances to large industrial compressors. About 25% of the world's electrical energy is consumed by electric motors in industrial applications, which can be considerably more efficient when used in conjunction with an AC Variable Speed Inverter Drive, saving both energy and money.

Why the HD1?

When selecting an AC inverter, two important factors are performance and price. Performance because you need to ensure your inverter can cope with the most arduous applications, and price because AC inverters are often about saving energy, and a short pay-back time on capital expenditure is key. The HD1 delivers on both these counts.
