Product information
Overview
Key Features
- Optimum power and speed: Optimum power is 1.2 kW at an optimum speed of 4,500 rpm.
- Synchronous motor design: Permanent-magnet synchronous motor with High Dynamic motor type.
- Encoder feedback: Encoder IC22DQ incremental Encoder: 22 bits, resolution 4194304, encoder-internal 2048 S/R, plus commutation position 11 bits, with DRIVE-CLiQ interface.
- Mechanical configuration: IM B5 (IM V1, IM V3) design with M23 connector size, rotatable signal and power connectors, and a shaft with fitted Feather key.
- Cooling and protection: Natural cooling and IP64 degree of protection.
- Brake and monitoring: Without holding brake; temperature monitoring uses a Pt1000 temperature sensor.
