Specifications:
The document outlines the specifications for various gear and motor combinations, including worm gear S 769, S 668, GS 3, spur gear M 10, planetary gear PM 60, rotary encoders RV20, RV30, RI20, RI30, and brake B77. The electronics are integrated, and the dimensions and characteristics for types MQC637 and MQC667 are provided, with lengths of 112 mm and 142 mm respectively.

Brushless DC Drive Properties:
The drive features a brushless DC motor with integrated commutation electronics and rotor position sensing using three hall sensors. It includes a K4 terminal box for power supply and sensors, and can be controlled via CAN-Bus (CANopen, Drive Profile DSP-402) or digital/analogue I/O. The rotor is an 8-pole neodymium magnet with slight detent torque, offering a service life of 20,000 hours under S1 duty. The insulation material class is F, with a system protection rating of IP 44, optionally up to IP 65. The supply voltage ranges from 24 to 48 V, with special models available upon request.

Performance Parameters:
The nominal power ranges from 117 to 180 W, with nominal speeds between 3300 and 3650 rpm, and nominal torque from 0.31 to 0.47 Nm. The nominal efficiency is between 86% and 91%. Short-time duty torque and speed are also specified, along with idling speed and current.

Environmental and Mechanical Specifications:
The drive operates within an ambient temperature range of -20 to +40°C, with a maximum stator temperature of +155°C. The shaft diameter is 10 mm, with maximum axial and radial forces of 40 N and 400 N respectively.

Gear Unit Combinations:
Various gear unit combinations are detailed, including planetary gear PM 60, spur gear M 10, and worm gear S769, with different reduction ratios and corresponding rpm and torque values. All torques are calculated with a duty factor of 1, and additional combinations and reduction ratios are available upon request.
