About Gear Units & Motors
Moventis gear units and motors are selected based on the precise power, torque, and speed requirements of each conveyor system. The combination of a correctly sized electric motor with a compatible gear unit defines the efficiency, service life, and operating cost of the entire drive package.
Electric motors are specified by output power, rated speed, efficiency class, and frame size. IE3 and IE4 class motors reduce energy consumption and comply with current regulations.
Frequently Asked Questions
Motor power is determined from conveyor length, throughput capacity, material type and condition, belt speed, and duty cycle. These parameters feed into a base power lookup and are then multiplied by material, condition, and duty factors to produce the minimum required shaft power. The result is rounded up to the nearest standard motor rating.
Helical gear units are the standard choice for conveyor drives — they are compact, efficient, and available in a wide range of ratios. Bevel-helical units are used when the motor shaft must be perpendicular to the output shaft, or when very high gear ratios or torque levels exceed what a single-stage helical unit can provide.
The gear ratio is calculated by dividing the motor speed (rpm) by the required drum speed (rpm). Drum speed is derived from the target belt speed and drum diameter. The calculated ratio is used to select the appropriate gear unit size and type from the available range.
IE3 and IE4 designate high-efficiency motor classes under IEC 60034-30. IE3 is the minimum standard in most markets; IE4 offers further energy savings, particularly relevant for high-duty and variable-speed applications. Higher efficiency reduces operating costs and heat generation, extending motor life.
Yes. Moventis can supply pre-assembled motor-gearbox units (motoreduce) in foot-mounted, flange-mounted, or shaft-mounted configurations. This reduces installation time, ensures shaft alignment, and eliminates coupling selection from the scope of work.
Conveyors are typically classified as S1 (continuous duty) for steady throughput operations, or S3/S6 for cyclic or intermittent loading. The duty class affects motor thermal sizing — higher intermittency allows a smaller motor frame; continuous heavy-duty operation requires a motor rated for S1 at full load without derating.
