This document provides comprehensive mounting and operating instructions for SIMOGEAR geared motors, specifically focusing on motors designed for mounting onto SIMOGEAR gearboxes. It covers various aspects from initial delivery to final disposal, ensuring safe and professional handling.
Function Description
SIMOGEAR geared motors are partly completed machines intended for stationary use in general mechanical engineering applications. They comply with harmonized standards such as EN 60034 (VDE 0530) and are not approved for operation in hazardous zones. The motors are designed for surface cooling with cooling ribs, where an external fan draws air over the stator housing. IC411 forced ventilation is standard, with IC416 forced ventilation available as an option. A non-ventilated variant, IC410, is also available for special cases. Condensation drain holes are provided to prevent corrosion and maintain clearances, located at the drive end (DE) and/or non-drive end (NDE) depending on the mounting position.
Motors can be optionally equipped with mechanical backstops, which permit only one direction of rotation during operation. These backstops are fitted with centrifugally operated sprags that become wear-free when the drive speed exceeds a certain threshold. Spring-operated disk brakes are also optional, electrically released to reduce motor run-on times or hold loads. These brakes are designed for DC operation and can be controlled directly by DC voltage or via a rectifier for AC voltage. L/LS brakes can be encapsulated for dust and moisture protection, and some versions offer low-wear friction linings or microswitches for brake status monitoring.
Various rotary encoders are available to sense speed and position, including DRIVE-CLiQ, incremental, and absolute encoders. Functionally safe rotary encoders are marked with a signal yellow on the fan cover and "SI04" on the rating plate. Motors can also be prepared for customer-supplied encoders, with a shaft end designed for a maximum total weight of 500g. For 4-pole motors, a free second shaft end can be supplied at the NDE, capable of transmitting full rated power. Handwheels are available for motor frame sizes 71 to 160.
The motors are designed for operation with converters, with the converter world motor or synchronous-reluctance motor being recommended. These motors typically feature an improved ("Advanced") insulating system and are controlled by the converter.
