Fractional HP Clutches/Brakes - 4

Selection Process STEP 1 These graphics provide a visual guide to unit mounting in a typical installation. PB The brake will be mounted on a driven shaft with the magnet secured to the machine frame. When engaged, the brake will bring the rotating load to a stop and hold until power is removed. SF/SFP The SF or SFP clutches are designed for parallel shaft mounting and will connect to the load via a chain or belt drive. The clutch can be mounted to either a driving or driven shaft. SFC The SFC clutches are designed for use with two in-line shafts. Half of the clutch will mount to the driving...

STEP 2 Determine the shaft speed at the clutch or brake location. Whenever possible locate the clutch or brake at the highest speed shaft available to perform the desired task. A higher speed will provide a lower torque requirement and therefore a smaller clutch or brake. STEP 3 Use the chart below to find the intersection of the speed and torque for your application. This will provide the unit size. STEP 4 Using the appropriate catalog page confirm unit dimensions and mounting. Provide unit bore size(s) and coil voltage. For additional calculation formulae and dynamic torque curves, please...

Determining the Clutch or Brake Size First, determine which style clutch or brake you need. The type of unit selected depends upon the function to be performed. Next, determine the size of the clutch or brake. There are two methods you can use to calculate the dynamic torque required. Warner Electric clutches and brakes are rated by static torque. The clutch or brake size can also be determined using the selection chart. Find the intersection of the prime mover horsepower (HP) and shaft speed at the brake using the selection chart on Page 4. The relationship between the horsepower and speed...

Selection Criteria Response Times for Clutches & Brakes Response Times Notes: 1. Torque decay time is dependent on the type of arc suppression circuit used. Decay times shown in table assume use of a diode in parallel with the coil for arc suppression. If no arc suppression is used, torque will decay almost instantly. 2. Actual response times depend on several factors such as inertia being accelerated or decelerated, speed, load torque, and type of switching used. 3. Time to full torque can be shortened by applying overexcitation voltages up to 50 times the rated coil voltage. 4. The time...
