Product Description:
Bosch Rexroth designs the 3-phase induction motor 2AD134D-B35OA1-CS07-B2N1 for motion control in automation systems. It is equipped with a digital servo feedback along with multiturn encoder that provides absolute accuracy of 0.009° and a relative accuracy of 0.01’. This feedback system also features to maintain position upon sudden power shutdowns.
The 2AD134D-B35OA1-CS07-B2N1 induction motor has an integrated axial blower that delivers a constant air flow of 1000 m³/h from side B to A through the motor enclosure and it consumes 170 VA of power. The motor has a nominal current usage of 52 A and 26 kW power utilization under normal conditions. It has a mechanically balanced key shaft with an imposed sealing ring to achieve an overall IP65 rating from external intrudes. The 2AD134D induction motor provides both flange and foot mounting options of installation to allow flexibility in vertical or horizontal mounting on machines. It possesses a rotational angular inertia of 0.118 kg·m² and has the maximum revolving speed capability of 7500 RPM with its built-in standard ball bearings. It develops nominal torque of 166 Nm and requires an operating voltage source of 387 V. The 2AD134D induction motor comes without a holding brake in the initial assembly and it weighs 135 kg on its own.
The 2AD134D-B35OA1-CS07-B2N1 induction motor has a base operating speed of 1500 RPM and produces a sound pressure of 75 decibels at one meter distance. It has a wide ambient thermal range of 0 to 45 °C and it offers a winding insulation of class F to cope with high temperature sites. The 2AD134D induction motor has a thermal time constant of 55 minutes to effectively manage temperature during continuous duty cycles.
Frequently Asked Questions about 2AD134D-B35OA1-CS07-B2N1:
Q: How does the axial blower contribute to motor efficiency?
A: The axial blower maintains internal temperature stability, allowing continuous high-speed operation without thermal derating, especially in enclosed or high-demand environments.
Q: What is the benefit of IP65 shaft sealing in this motor?
A: The IP65 rating protects against dust ingress and low-pressure water jets, making the 2AD134D-B35OA1-CS07-B2N1 reliable in harsh or contaminant-prone environments.
Q: Why is a mechanically balanced full key shaft important?
A: This shaft type ensures reduced vibration and mechanical stress, enabling higher-speed operation and better alignment with connected machine components.
Q: What type of bearings are used and why?
A: The motor uses standard ball bearings that support high-speed rotation up to 7500 RPM while reducing friction and enhancing lifespan.
Q: Why is a thermal time constant of 55 minutes significant?
A: It indicates how long the motor can sustain heat buildup under load before thermal limits are reached, allowing safer operation over prolonged cycles.
