Compact high torque motors

16 August 2019

Offering high levels of torque and precision, the latest torque motors from Motion Control Products have an integral strain wave (harmonic) gearbox. With high efficiencies and compact sizes, they are available in four series: MAS, MAT, MAH and MGM.

The all-in-one MGM series has an integral torque motor, encoder, brake and servo drive. Delivering a high precision of up to 60 arc sec, their high torque of up to 557Nm makes them ideal for a host of application, demanding low noise, high torque and precision control, such as collaborative robot applications for loads of up to 25kg. Integrated servo drives for EtherCAT or CANOpen enable the units to interface with most mainstream controllers on the market. A hollow shaft simplifies system design by allowing the passage of cables, pipework etc.

The other series of low cogging, low noise motors have an integrated strain wave gearbox and frameless motor with a range of encoder options. One series is the MAH, which have a standard hollow shaft and frame sizes from 60mm to 145mm diameter. Rated torques of up to 800Nm are available and precision is up to 30 arc sec.

The MAT series have a wider hollow shaft and offer a precision of up to 40 arc sec, while the MAS series have a solid shaft and a precision of up to 50 arc sec.

Across the whole series, all the models are flexible, reliable, low maintenance and compact. Gear ratios are available from 51:1 to up to 161:1. All models are fully enclosed and self-cooled and can be specified with IP67 ingress protection when operation is required in harsh environments.

Standard input voltages are 48VDC, 110VAC and 220VAC, and input voltages can be customised on request, as can the torque etc.

As well as robotics and factory automation, applications for the versatile motors include electronic and semiconductor equipment, medical equipment, precision measuring instruments, machine tools, laser processing and spray-painting equipment.
