Hitachi HTW Serie (New)

The new Hitachi TorqueWire series of integral servo systems sets a new style in complex automatic machinery architecture. Hitachi TorqueWire motors are complete, self-sufficient servo axis building blocks which allow the design, integration and operation of large multi axis-systems with minimum hardware and surprising ease. The Hitachi TorqueWire motor system consists of an advanced, high performance rare earth brushless servo motor, a DSP based, high voltage interpolating servo drive and a single or multi-turn absolute encoder, all assembled in a very compact IP67 protected frame.

The motor systems are controlled via a multi-drop EtherCAT field bus, linking together groups of motors on a single bus system. The motors are supplied from a common DC bus and braking energy from any drive is intrinsically recycled on any other axis on the network. The performance of Hitachi TorqueWire originates in the advanced design of both motor and drives.

Main features :

• Typical Supply Voltage Range: 310 – 560 Vdc
• Rated Torque Range: 2,4 Nm – 70 Nm
• Type of cooling: natural convection, water cooling and fan cooling (only for HTW07 models)
• Servo Integrated Drive
• Endat Heidenhain Absolute Encoder single or multi-turn (280 arcsec accuracy) or two-pole resolver
• Integrated RFI filter Class B
• Protection degree: IP67

Main Application :

HTW Motor Series create a different approach to complex automatic machinery architecture They are complete, self-sufficient servo axis building blocks which allow the design, integration and operation of large multi-axis systems with minimum and simplified hardware.
