High Temperature Stepping Motors Field of application The standard stepping motors from the MICROSTEP series are generally permitted for operation in ambient temperatures ranging from +5° to +55°C. Use in the frost range as low as -20°C is certainly possible as long as the customer can ensure that no condensate gets into the motor. In most cases, use at higher temperatures is what is more critical. For this reason, we have developed stepping motors with a special structural design and optimised the selection of materials that allow the motor to be used in ambient temperatures up to 90°C. If the electronics of the motor are configured properly and the controller is adapted, ambient temperatures of over 100°C are possible. Functional description Each MICROSTEP stepping motor in the SHS 39/200-0100 to SHS 39/200-4000 series can be constructed to work at high ambient temperatures. The basic winding geometry and, therefore, the electrical parameters remain the same. Due to the slightly larger air gap present in the high temperature motors, the torque is somewhat less than with standard step motors. Roughly 10 to 15 % less torque can be assumed at a comparable operating frequency. The standard motor connecting leads are 400 mm long and are Teflon-insulated. The degree to which coupler connectors can be used depends on the type of connector and position of the mating connector. In most cases, the electronics are located outside of the critical temperature section. Along with the stepping motors, it is also possible to set up linear actuators of the LA 71 and LA 72 series for higher temperatures. M 3x -5 (e1... e4) The SHS 39/200-1651 stepping motor was developed as a typical example. It is used as a high temperature motor in illumination systems and is designed for constant ambient temperatures of 80°C. 33,6 -0,6 15 ±0,1 e3 e2 rt 45 -5 4,6 -0,1 e1 0,8 ± 0,1 ø 22 -0,025 31 ± 0,1 39 ± 0,23 e4 17 ±0,6 ø 5 -0,005/ -0,011 39 ±0,23 31 ±0,1 sw ge bl 0,03/9 PTFE-5 isoliert Schrittwinkel Sw/ o 1,8 ° Haltemoment Phasenstrom MH/ mNm IPh/ A 120 Phasenwiderstand Phaseninduktivität RPh/ Ohm LPh/ mH 0,5 9 13 Rotorträgheitsmoment JR/ gcm2 17 Lastmoment bei 1 kHz Schrittfrequenz ML/ mNm Motorgewicht m/ kg 0,16 Phasenanschluss: Phase 1 - Anschluss 1(rt) und 3 (bl) Phase 2 - Anschluss 2 (ge) und 4 (sw) Hinweise Anzugsmoment der Befestigungsschrauben : 0,8 Nm + 0,05 - 0,1 Zugelassen für Umgebungstemperaturen von 80°C Maßstab Benennung Schrittmotor ÄZ 2009 Mittlg Datum Konstr. 30.01.
