Selecting DC Motor Speed Controls for PMDC Gearmotors

Selecting DC Motor Speed Controls for PMDC Gearmotors

Basic DC motor speed controls accomplish the conversion of AC power to DC with varying degrees of DC voltage “purity.” For proper control selection you’ll need to identify which performance criteria are important to your application. We’ll review how different speed controls affect the quality of DC output and consequently, the performance of your DC

Design Tips for Gearmotor Applications

To select the best gearmotor for an application, one must go into more detail than just selecting the best suitable output speed and torque. Here are five criteria you should consider. 1. Gearmotor Mounting Orientation Gearmotors are typically designed to be mounted with the gearbox level with the motor, and with the drive shaft in

Selecting Fractional Horsepower (FHP) Gearmotors for Long-Life Applications

Selecting Fractional Horsepower (FHP) Gearmotors for Long-Life Applications

Buyers should first decide what kind of operating life is needed. If durability is not an issue, or if the duty is so intermittent that even a short-life (“throw-away”) motor will translate into years of operation, then you’ll want to go with the best price. But if product quality and reputation depends on reliability and

Measuring Armature Circuit Resistance in a PMDC Motor

Measuring Armature Circuit Resistance in a PMDC Motor

Application Notes & Gearmotor Tips: When a permanent magnet DC (PMDC) motor fails to operate properly, or fails to run at all, one sensible troubleshooting step is to measure the winding resistance to determine if there’s an open circuit or a short circuit, either between turns of the same winding, between two windings in the

What is an AC Torque Motor? When do I use one?

What is an AC Torque Motor? When do I use one?

Bodine Electric offers AC induction motors that are impedance protected – we call these types of motors AC Torque Motors. These motors are ideal for tensioning applications because they can operate in stall mode without overheating. Torque motors feature: Higher starting torque at lower speed and lower running torque. What does “impedance protection” mean? It

“Hotrodding” AC Capacitor Motors and Gearmotors …At your own Risk

You can get higher starting torque from an AC induction motor by replacing factory specified capacitors with larger ones. But pushing the motor too far beyond design specs is risky. Here’s how capacitance affects motor performance. Overview Capacitors for permanent-split-capacitor (PSC) and capacitor-start (CS) AC induction motors are sized by motor manufacturers to produce

Peak or Obtainable Torque from small (FHP) Gearmotors and Motors

Peak or Obtainable Torque from small (FHP) Gearmotors and Motors

It can get confusing when we discuss “Peak” or “Obtainable” torque for small (fractional HP = less than 1HP/746W) gearmotors and motors because terminology and definitions sometimes change between AC and DC motors, gearmotors, or when a motor speed control is used. AC Motors: in non-synchronous AC induction motors, we define obtainable torque as breakdown torque.
