Load Testing with Gearmotors -- Know Your Current, Know Your Load

Load Testing with Gearmotors — Know Your Current, Know Your Load

Load Testing a Drive Application with a Brushless DC Gearmotor and Control By Eman Elashye When designing a new piece of equipment that uses motors or gearmotors, design engineers must calculate how much motor torque will be needed to drive their application load. If the gearmotor or motor is undersized and too small, the product

Considerations for Traction Motor Applications -- AC, BLDC or PMDC Motors

Considerations for Traction Motor Applications — AC, BLDC or PMDC Motors

A ”traction motor” is a motor or gearmotor used in a traction application. Golf carts, electric vehicles, locomotives, lift trucks, etc. Often “traction motors” also have mounting features, temperature sensors, wiring terminals that are useful in mounting the motors in a vehicle. They may also have a higher level of environmental protection against dust

High-Performance Type “48B” Brushless DC (ECM) Motors and Gearmotors

Type 48B Brushless DC Motors and Gearmotors from Bodine The new special-order 48B is twice as powerful as previous BLDC motors from Bodine. Delivering up to 1.5 HP (1100 Watts) output at 260VDC (3000RPM), it brings all the benefits of brushless DC technology to applications that in the past might have required higher-cost servo motors.

What is a Sensorless Brushless DC Control? How does it work?

What is a Sensorless Brushless DC Control? How does it work?

A sensorless brushless DC control consists of a power supply, a power stage, commutation logic, and startup logic. The key difference to an electronically commutated BLDC motor system is that the Hall sensor inputs are replaced by a system that measures generated voltage (BEMF = back EMF) and uses zero crossings to determine when to
