The G500-B + M650-U + i550 motec Bevel Gearmotor combines Lenze's G500-B bevel gearbox with an M650-U motor and an i550 motec frequency inverter mounted directly on the motor, forming one compact mechatronic unit. Designed for 120 Hz and rated IE5 to IEC TS 60034-30-2 (Grade 2 under GB 30253-2024), the motor is a sustainable choice where a very wide speed setting range is needed; it is two frame sizes smaller than an IE3 equivalent, and its low mass moment of inertia suits dynamic tasks.
Because the inverter sits on the drive itself, speed is adjusted locally without a separate control-cabinet inverter, and sensorless operation delivers up to 250% starting torque from standstill. As the units hold most international approvals they can be installed in machines worldwide, and their high efficiency class helps operators qualify for regional or market-specific efficiency incentives.
The right-angle G500-B bevel gearbox handles high permissible radial forces and offers closely stepped ratios with low backlash. The range spans 0.75 … 22 kW and output torques of 8 to 4300 Nm, with ratios up to i = 2935 in 2-, 3- and 4-stage designs.
Features
120 Hz, two sizes smaller
The 120 Hz IE5 motor is two frame sizes smaller than an equivalent IE3 solution and suits dynamic applications.
Integrated i550 motec inverter
The i550 motec frequency inverter on the motor provides up to 250% starting torque from standstill in sensorless operation.
Right-angle G500-B bevel gearbox
The highly efficient bevel gearbox takes high permissible radial forces with low backlash and closely stepped ratios.
Wide setting range, low inertia
A large speed setting range and low mass moment of inertia ensure optimum operation at variable speed.
Applications
- Horizontal conveyor and materials handling systems
- Warehouse logistics and automated storage systems
- Airport baggage handling and courier, express and parcel (CEP) facilities
- Food, beverage and packaging machinery
