Description
70KTYZ Permanent Magnet Synchronous Motor – Dimensional Drawing (mm)
Product Overview
The 70KTYZ is a permanent magnet synchronous motor with a built-in gearbox. It delivers low-speed rotary output for equipment and machinery that require controlled motion.
Changzhou Xinghua Electric offers several rated voltage options: 24V, 100V, 110V, 120V, 220V and 230V AC.
Customers can choose configurations for 50Hz, 60Hz or 50/60Hz power supplies, depending on their requirements.
The motor supports controllable clockwise and counterclockwise rotation, giving equipment manufacturers more flexibility when designing their drive systems.
