Specifications:
The document outlines the recommended combinations for various gears and components, including worm gear (S 668), spur gear (M 7), planetary gear (PM 50), rotary encoder (RV 30, RI 30), brake (B 77), and electronics (mcDSA-E45 or mcDSA-E65). It focuses on the MQ 5 Brushless DC motor, which operates on an external standard controller with block commutation and rotor position sensing by three hall sensors. The motor features a 4-pole neodymium magnet rotor with low cogging torque and a service life of 20,000 hours under S1 duty. The insulation material class is F (155°C), and the system protection is IP 44, optionally up to IP 65 (IP 69). Special versions for short-time duty with higher performance and additional voltages and speeds are available upon request. Options include thermal protection, special shafts, special flanges, and stainless steel.

Dimensions and Performance:
The document provides dimensions for two types: MQ 543 (112 mm) and MQ 563 (132 mm). Both types have a nominal voltage of 24 Volt DC. The MQ 543 has a nominal power of 70 W, nominal speed of 2890 rpm, nominal torque of 0.23 Nm, and nominal efficiency of 0.64. The MQ 563 has a nominal power of 114 W, nominal speed of 3110 rpm, nominal torque of 0.35 Nm, and nominal efficiency of 0.69. Both types have a torque constant of approximately 5 Ncm/A and can handle a maximum current and torque three times their nominal values.

Electrical and Thermal Properties:
The idling speed is 4000 rpm for MQ 543 and 4100 rpm for MQ 563, with an idling current of 0.7 A for both. In short-time duty (S2 5min), the MQ 543 can reach a speed of 2400 rpm and torque of 0.35 Nm, while the MQ 563 can reach 2500 rpm and 0.55 Nm. The terminal resistance is 1040 mOhm for MQ 543 and 600 mOhm for MQ 563, with terminal inductance of 765 μH and 495 μH, respectively. The motors can operate in ambient temperatures from -20 to +40°C, with a maximum stator temperature of +155°C (ISO F).

Mechanical Properties:
The shaft diameter is 10 mm for both types, with a maximum axial force of 40 N and radial force of 400 N. The weight is 1.2 kg for MQ 543 and 1.4 kg for MQ 563, with moments of inertia of 180 gcm² and 260 gcm², respectively. Other gears and extensions are available upon request.
