R911284548
Bosch Rexroth Indramat presents the R911284548 (MHD112C-024-PG0-LN), a product from its MHD servo motors range. Known for their diversity of function and applicability to a variety of industrial automation applications, Bosch Rexroth’s MHD motors are permanent magnet synchronous motors, offering an advantageous torque to inertia mass ratio that makes them ideal for high dynamic operations. Their robust construction promises high reliability and the ability to perform seamlessly under harsh environmental conditions.
The R911284548 (MHD112C-024-PG0-LN) is a prime example of an AC servo motor within this range. Its distinguishing feature is the incorporation of a digital servo feedback system that includes an integrated multiturn absolute encoder, designed to detect the indirect absolute position within 4096 motor revolutions and retain axis position even during voltage loss. Operating with an optical measurement method, this encoder system has a ±0.5 angular minute accuracy level. The R911284548 (MHD112C-024-PG0-LN) motor's design ensures natural convection or surface cooling. Furthermore, it is equipped with a temperature monitoring system to guard against thermal overload. The integral bearings cater to high radial loads, enabling the direct mounting of pinions and belt pulleys. These bearings remain permanently lubricated, making the motor virtually maintenance-free. With 4 pole pairs, a rotor inertia moment of 273 x 10-4 kgm2, a maximum speed of 4000 rpm, and a peak theoretical torque of 148.0Nm, the motor operates efficiently within a 0 to 40°C temperature range.
