This maximum temperature allowed may not be exceeded at the motor surface (measured at the stator housing – near the cast connection box). The motor temperature reached during operation, depends on various factors: e.g. motor phase current, speed, ambient temperature, duty cycle, forced draft, heat flow to other bodies, ...       For extreme applications STÖGRA offers motors with extended operating temperature:                 Type   Temperature range           Z240   -40 °C until 100 °C (short time until 120 °C)   Z80   -40 °C until 120 °C (short time until 130 °C)   Z153   -50 °C until 100 °C                 • ordering examples: SM 87.2.18M6 Z240, SM 88.1.18M4 Z80       On request STÖGRA also offers further versions, e.g. for low temperature applications from -60 °C, or high temperature until 200°C Please contact us for details.               Download         stepper motors special versions – data sheet (56 KByte)         stepper motors catalogue 2016 – Catalogue (850 KByte)           stepper motors  I   position controls  I   power amplifiers  I  equipment   I  home  I  info@stoegra.de
